I haven't purchased one yet but had the opportunity to stop by the local  store for a quick 30 minute demo. I was sold on the idea before even touching one and that quick session was enough to make it a rock solid deal (waiting for the 3G one).

The "tabs" on safari need an improvement. I instinctively tapped and held so I could reorganize them but they didn't budge. Still, it gets an 11 out of 10 stars in my book.
