I'm in the market for a nice, light netbook, and I've been wondering if it might be worth spending the extra money on an iPad instead. What I'd be using it for mostly is writing, though. I use Google Docs anyway, so I don't need a full-featured word processor, and of course I'd get a plug-in physical keyboard. So my question is, how well does Google Docs work on the iPad? Is it as quick and easy to use as on a PC?
