larger is good, I ave one, and I loves it. (with logi keyboard – slightly thicker than apple keyboard but better action, has function keys like volume etc, and they are backlit).
Splitscreen working on the big iPad is genuinely fabulous, it makes it, for most worky things, better then a laptop. If only powerpoint made it easier/possible to work on multiple ppt decks at the same time, I’d never open my hateful windows dell pish again.
Only downside – games that require you to hold and either tilt the machine, or use virtual dual sticks, are a bit daft on sucha big machine.
movies look awesome, although if your travelling the whole flight can watch with you = carefull with content! (true blood was a bad idea…)
