They sound attractive because they run full Windows. But what are the catches? Do they make it worthless or is it still a useful tool? Are these issues to consider? - finger touch inaccuracy (and slowness) compared to mouse input - high battery consumption and slow recharging - low RAM on affordable ones (just 2 GB) I'm really tempted to buy one so I can get it out of my backpack and do some work (even just a little) while commuting. In this situation I can't just take my laptop with me. But is it worth it? Surface Pro is out. It's expensive like a MBA.
