I played with an iPad2 at Best Buy prior to purchasing a 3g Gen 1 from AT&T online for about half the going rate for the Gen 2 (refurbed 64Gig for $429). Been using if for a month and I really like it. If I have a lot of web pages open where I am going back and forth between pages I see some slight delays. I believe that is the small amount of RAM issue with the Gen 1, however; I saw some slight delays on some pages when playing with the Gen 2, so, there are a lot of factors at work when surfing with a mobile device.
I purchased Infinity Blade and had a kid comment on how good the graphics looked. I know that the graphics engine (if I am using the term correctly) is faster on the Gen 2 but since the screen and resolution are the same I don't think it matters that much in everyday use. I don't plan on playing with any Gen 2s for awhile though, as earlier posters said, if you are using the Gen 1 you won't notice 😉
I surf, some light gaming, note taking, calendar management, email, and play around with various apps. I do some longer writing with a full size blue tooth keyboard case (Rocket Fish). I am getting a lot of use out of it. It has replaced my Franklin Dayplanner and also my laptop for many things. I carry a lot of photos on it, some videos, and some music. I bought the camera kit and after taking some photos I just put them on to the iPad, tweaked them a little with Photoshop Express and sent them off. It is a nice device.
Now I have to get my family to buy me an iCade.
