These are the exact reasons I'm waiting for a comparable Android tablet.
You get the watered down GUIfication element, where anyone can pick it up and it 'just works'
You also get the ability to really dig in via the ADB console or terminal apps.
I'm certainly no majority example, but this seems to me to be 'done right', and I'm excited to buy one for my girlfriend.
Until a good KB dock-type attachment comes out for Android tabs, however, I've got no real use for it - I spend a vast majority of my 'computing' time using the keyboard, to a point that I've gotten a full-size USB keyboard to attach to my laptop which also has a full-size keyboard that just isn't quite as comfortable.
Until I've got that same flexibility with a tablet, it's just not my thing. My girlfriend is of the opinion that iPads are too locked down, and therefore useless, and she's 1/10 the computer nerd that I am.
