Like most people, and the pro reviews, the ipad is huge winner.
Ignore the specs and the capabilities; this device is about the experience. And it is almost universal that the enlarged ipod touch, if that's all it is, is something totally different. Yes, it's just more pixels, but most people would agree that hdtv vs standard tv is a whole new ballgame, too. But that's just more pixels as well.
It's not just what the ipad can do; it's how you do it that makes it so desirable. I too was not expecting much. I was not completely wowed with it at the store. But I knew personally that I wanted an ebook reader, a movie player, and a web surfing machine so I bought it. My impressions have steadily improved as I have been using it at home. My ohmygosh moment was when I tried to type on it. I was shocked that I could type quickly and accurately on it. That was when I realized that the game had changed.
