If I was getting my mom a pad, it's the Apple.
If I was getting a pad for me to do notetaking, it's the Apple.
But what do I own? No less than 4 droids. Why? Because I author a few apps that were on PalmOS, then WinMo and because Apple locked out Bluetooth SPP I can't move our apps to iPhone or iPad. If it wasn't for that, the choice would be Apple.
Maybe there will be a great note taker apps soon but for now the droid seems to be a fav for games.
One thing I've been thinking about when considering getting a tablet, an iPad 2 in particular, is that I can use it as a second monitor for my MacBook Pro. It's almost the same size screen, and considering how much I move my MacBook around, it would be good to have a "second monitor" that's equally as portable.
