I just picked up the 10.1" model after borrowing a friends 8.9". The real selling factors were the price, the access doors on the bottom, and the 5800mah battery which I got, though I heard some later shipments will have a 4400mah battery.(?) As stated with the 10.1" you don't really get more real estate but things displayed are slightly bigger. In the store having the 8.9" right next to the 10.1" I was able to put the 8.9" on top of the 10.1" and the difference to me really isn't that big in feel and portability for me. I understand some people want the smallest package but to me the 10.1" is in no way getting to the point of just going with a regular size laptop. Dell has a 12" mini and that to me is getting to that point of why bother? I sold an Inspiron 15" laptop and that thing was huge in every way compared to my 10.1". I guess it comes down to personal preference in the end. I do think they should have included the N wireless card and the 1.3MP camera most other brands have but for how often I'm going to use the camera it didn't matter and the wireless can easily be upgraded cheaply enough down the road if wanted.
