My feeling is that the iPad is considered better than laptops and netbooks because the Big Three operating systems (Windows, Mac, and Linux) are too complex for the vast majority of users. Of course, a simple OS should be possible on a non-tablet, non-phone device, but there's just too much baggage to just start from scratch. The iPhone/iPad had a clean slate.
