I have an 11" MBA, which is very very mobile. The footprint is so close to the first iPad that I think you can carry with you an MBA every time you can carry an iPad. The iPad 2's case could be different, though. With a thinner and lighter profile, it can make a little more sense to own a tablet. I'm not yet completely convinced, though. Money isn't that disposable for me (and probably for many others) so I want to make sure the purchase will justify the cost. iPad 2 will offer greater intimacy during content consumption, new apps that can only be experienced with touchscreens, a slightly (?) smaller footprint, etc; but do those benefits justify the huge overlap between the tablet and the ultramobile razorsharp 11" Macintosh? I know, at the end of the day, it will boil down to my willingness and ability to spend, but I'd like to hear your thoughts.
