Battery Life – Should last prolonged use in class at school without the need for recharging.
Weight – Should be light enough for your child to carry around all day.
Wireless – Must be dual-band capable, and state that it has a/g/n, or a/b/g/n.
RAM – Should be 4GB or more, or else programmes may be much slower to run.
CPU – Faster is usually better, but may also reduce battery life. Often the applications used in option subjects such as Art, DTG and Graphics etc require a faster architecture.
Hard Disk Drive – Students will be using their school Google Drive accounts for storage (cloud).
You may decide what size hard drive will be suitable for personal/home use Some newer devices may feature SSD drives, which are faster, lighter, are more reliable and give longer battery life, but they are also more expensive.
Robustness – Your device should be strong enough to survive being knocked about a little. Check also that the hinges are robust as some of the cheaper devices are quite weak.
General Protection - A suitable carry case or protective sleeve.
Software - For general class use, no additional software will need to be purchased. Some subjects may require specialist software and where possible free public domain software will be sufficient (as recommended by subject teachers)
