I was drawn to the iPad for the whole 'lean back' experience. I'm looking forward to using it for web browsing, e-mail, ebook/newspaper/magazine reading etc while slouched on the couch.
Most nights I spend a couple hours on average watching TV with my spouse, and they're not always shows I particularly like. (I like shows like 'Fringe' and 'Criminal Minds', he likes shows like 'Psych', and various reality TV and/or CSI-type shows). We each tend to start using our laptops during the shows we're less interested in (Otherwise I'd go nuts the 18th time the camera lovingly focuses on someone shaking a test tube during a CSI show, or some narcissistic reality show "star" bitches about another person and then bursts into tears).
In any case when doing that I end up balancing my laptop on the couch's armrest, or if I'm especially slouched down, on my chest. (My lap is not an option because a very insistent cat is usually already there.) I'm sick of doing a tyrannosaurus rex imitation every time I have to type, and think an iPad would be the *perfect* device for these situations.
Plus, I've always been attracted by the tablet form factor (had a toshiba convertible for a couple years but didn't like needing a stylus and it was still too bulky.) I think the iPad will serve perfectly as my 'lean back' device of choice in these situations. I can't wait!
Wow, I have a very similar situation and want the ipad for the same reason. I have a macbook I currently use, but it gets really hot, the battery is dead on it so it always has to be pluged in, I have to prop it up on a pillow, and the couch is a bit tight with my laptop there, and my girlfriend using her laptop, and a cat also. It will be so nice to just lay back with the light ipad!
