It's funny--I was in bad shape for a bit with my wife yesterday. But then I let her play with it and browse the net and she ended up really liking it.
So far both Reddit and news.yc work perfectly. My Netvibes is a bit off due to some Javascript issue, but other than that it's been great for browsing.
I tried it today with my webapp too, and it worked great - with one exception. Whenever you have to type unusual characters it takes several extra keystrokes. But the zooming and viewing is simply amazing - I can fully use my webapp on a phone - wow. But being a bootstrapping startup founder, I can't justify buying it yet - I'll have to wait for the cheaper and more powerful version later on.
