aracer – the point is that it isn't a laptop sans keyboard. It's a different thing.
Everyone has had an ipad in virtually every science fiction film and now its here – what's not to like 😉
Seriously though, if you can't imagine schools making use of them, or doctors having patient notes on them, architects showing clients plans on them, etc. then surely that's just because you can't imagine things not being just like they are now?
'Only' 16GB? So what, data lives elsewhere. Quite possibly the processing power lives elsewhere too and you need to think of the ipad as a client device.
Who needs a 'proper' computer anyway?
