You may well have to compromise on screen size and weight: a 15in screen may offer more space and be easier on the eye, but it inevitably pushes up the weight. A 13.3in screen is normally a good compromise. Also consider how heavy laptops will be in bulk. Once five laptops are put into a carrying cart and moved around a school, even lighter machines can be too heavy to carry.Laptop battery life doesn’t compare favourably overall with the best-performing netbooks. Laptops range from between less than an hour to just over three hours when used intensively – running multimedia programs and video, for instance. Under light use, such as word processing or creating spreadsheets, this can vary between three hours at worst and nine hours at best. If the device is being used in lessons the battery life is crucial: there’s nothing worse than a laptop battery running out before the end of a lesson. Also bear in mind that, in a year’s time, that six-hour battery life will drop to around four hours. Don’t skimp on battery life if you can help it.If you’re connecting a number of peripheral items to the laptop, such as an interactive whiteboard, visualiser or data-logger, then you’ll need a good number of USB ports. Laptops tend to have between two and four of these.

Additionally, the majority of laptops now come with built-in memory card readers, allowing memory cards from digital cameras to be slotted straight into the laptop. Look out for laptops that offer xD compatibility as well as the usual SD and Memory Stick support.Laptops are easy to steal. Providing a laptop lock such as a Kensington-type device is a simple visual deterrent, but for the persistent thief with a pair of bolt-cutters this won’t be sufficient. It’s vital to use services such as SmartWater and Selectamark and scribe the laptop to make it unattractive to thieves.The Association of Chief Police Officers goes further. "The educational institution should conduct a regular audit of their ICT and produce a complete asset register,” it said in a statement on the Becta website."This way all schools can quickly identify which items of ICT may have been affected by criminal activity and the police will have a clear idea of what they’re looking for.” The addition of an asset tag to a device will again make it unappealing to the criminal fraternity.

Insurance is a decision to be agreed between the school and individuals if the device is being taken offsite. This can often be a cause for concern, so it’s worth discussing all the insurance options before allowing staff to use laptops at home or on trips.You don’t want to be teaching digital video and suddenly find that your device is operating as if it’s in slow motion. A laptop with 4GB of RAM is going to help overcome this issue, but if you’ll be using your machines for intensive tasks such as video editing we also advise choosing the fastest processor you can. It’s no good going by processor speed alone, either: if in doubt, aim for an Intel Core i5 or Core i7 processor if a laptop is going to be used for video editing, number crunching or CAD applications.If my consultancy conversations usually start with "so, you think your business is secure?", they invariably end with a response of "so, what can we do about it then?". This is where I really confuse them by not immediately talking about solutions and software, but instead about best practices, education and policy.

Formal information-security policies are often seen as the sole territory of larger enterprises, but this couldn’t be further from the truth. Every business – no matter how small – can benefit from implementing such a policy. The benefit runs much deeper than merely having a formal document: it really comes from the process of thinking about what data security means to your business, and creating a written, structured response to those needs. This process of thinking about security – and I mean really thinking about it, from top to bottom – is always an eye-opener for the team involved.Every business – no matter how small – can benefit from implementing such a policyEvery business – no matter how small – can benefit from implementing such a policy Even for those businesses at the smallest end of the SME scale, which are often only one bloke and his dog, this will be a team process. I’d never consider taking on a policy-creation job all by myself. This may not raise your opinion of how consultants work, but the bare truth is that unless policy creation involves those working at the coalface of the business, it’s totally pointless. The reason I can make such a sweeping statement can be best explained by making you understand what actually constitutes a security policy.

Strip it right back to its basics, and an information-security policy can be defined as a commitment to protect all the data that a firm creates and uses. Start fleshing out this simple definition, and the all-encompassing desire for data defence becomes your guide to exactly how the levels of required protection can be both achieved and maintained.Leaving this to a third party – or even delegating responsibility on a departmental basis – is security suicide: your IT bods (assuming you have such a luxury) may produce a technical draft, which is given a jargon-vacuuming by the personnel department, before finally being rendered totally incomprehensible by the legal department. A sustainable and effective security policy has to be written from the ground up, with input from the top down.Depending upon the size of your organisation, this could mean the sole proprietor meets with an outside consultant, or the board of directors works with the IT department, personnel, legal and the shop floor. The main point is that everyone must be represented, so your entire business is included; and that all foreseeable risks to the company’s data are mitigated as far as possible as a result.

One of the problems when talking about a security policy lies in ensuring that The Powers That Be truly understand that it should be – indeed must be – something practical and useful at a business level. This is especially true for small businesses, where information security is often regarded as an inconvenient interference with day-to-day work, rather than an integral part of the business process. An information-security policy – as with an acceptable-use policy or even a contract of employment – is useless if it’s merely signed and consigned to a filing cabinet until after a breach has occurred.I’ve heard IT security consultants talk about a policy document as being a "living, breathing, part of the business". Frankly, this is a step too far for me and most of the folk I work with. I prefer to think of it as a written information-security programme (WISP). In other words, it isn’t a bunch of boring files, but a collection of policy documents, along with the steps that need to be taken in order to enforce the policies they contain.

Some state governments in the US have even gone so far as to include this WISP requirement within their information-security legislation: Massachusetts, for example, requires every person who "owns or licenses personal information" to "develop, implement, and maintain a comprehensive information-security programme that is written in one or more readily accessible parts", and which contains administrative, technical and physical safeguards.I’ve started using this WISP definition as my take-off point when talking to a business about building a meaningful policy. I place that "readily accessible parts" phrase at front and centre of any initial policy-creation meetings. It’s crucial that everyone understands that "readily accessible" means accessible to all employees; this in turn means that suitable training and educational courses are available to them all.While that's small profit for such a massive firm - the company remains the fourth-ranked PC maker globally - Acer was expected to post a loss of NT$1.2 billion.The firm has struggled to post a profit since 2011, when its income dipped into a loss in the second quarter. It rebounded to a small profit at the end of that year and throughout 2012, before once again slipping into the red in 2013.

The troubles cost CEO JT Wang and President Jim Wong their jobs last year. Wang, who resigned in November, was supposed to be succeeded by Wong, but he stepped down before even taking up the role. The company has been run since January by Jason Chen.The company is trying to shift more of its sales out of the ailing PC market, and last week unveiled its first wearable, the Liquid Leap smart band.However, the bulk of Acer's sales continue to be in laptops and desktops, with the two form-factors making up 77% of its sale. It's struggled to get a foothold in tablets, which make up only 4% of its revenue - half of what they did last year.Intel and Google have unveiled a new generation of Chromebooks based on Haswell Core i3 and Bay Trail Atom processors - bringing the total Chrome OS market to more than 20 devices by the end of this year.

Core i3 models are confirmed by Acer and Dell, with Acer’s model set to go on sale in the US this summer at $349. The new devices promise a significant step up in horsepower from existing models using Celeron-branded processors."As HTML5-based apps do things like applying photo effects, or face detection, you’ll see the importance of performance,” explained Navin Shenoy, Intel vice president and general manager of the mobile computing group. Browser-based gaming and Google Hangouts were also singled out as applications that would benefit from greater processing power.For those seeking a more lightweight device, 11.6in and 13in Chromebooks based on the Bay Trail SoC were revealed by Asus, Acer, Lenovo and Toshiba, with US launch dates again set for this summer. Interestingly, Lenovo’s $329 N20P will include a touchscreen, a feature rarely seen on such devices - although precedents include Lenovo's own ThinkPad Yoga 11e, Acer's C720P and the £1,030 Chromebook Pixel.Shenoy predicted that a Bay Trail Chromebook could deliver 11-hour battery life, as well as thinner and lighter designs than were previously possible - including the first fanless Intel-based Chromebooks. He also promised that the coming generation of Bay Trail-based Chromebooks would for the first time bring 802.11ac to the platform.

A new ChromeBox - and the first ChromeBase Shenoy also demonstrated a new HP ChromeBox, a striking turquoise creation similar in appearance to the Intel NUC, and the first "ChromeBase” – a 21in all-in-one design from LG set to launch in the US later this month at $349.The LG ChromeBase is the first all-in-one PC running Chrome OS He wrapped up with the announcement that Chrome OS devices would be among the first to use "conflict free” processors, eschewing any materials from sources that finance African warlords.Caesar Sengupta, Google VP of product management, took the opportunity to announce a few new features for Chrome OS."Every Chromebook keeps getting better over time,” he declared. "This is what differentiates it from every other laptop on the market.”"We’re adding Google Now and voice actions into Chromebooks, so in the next weeks and months you’ll be able to do stuff with your laptops that’s never been done before. And within the next few weeks, Chromebook users will be able to watch their favourite movies and TV shows not only online, but also offline in the Google Play movies app.”
