Another Achilles Heel
I note that a number of things are mentioned as achilles heels of tablets (and also mobile phones) though one obvious one keeps on getting overlooked: powering them! It seems that with the increased sophistication of the plethora of modern mobile equipment rechargeable battery development hasn't kept pace and hence the time that these devices can run before they have be recharged has decreased. For example my low-end 2G mobile phone with a small battery has a stand-by time of about two weeks (even after 2-years use), whereas with my new Android smart phone with a much larger battery (even with WiFi, 3G and data turned off most of the time) I'd be lucky to get one week. It's all very well having all these mobile devices, but they won't work once the batteries run out.
