Ummm, isn't the killer app the web browser? Web browsing is the reason I got the 770 and 800. For those of us who are web addicted, there is simply NO equal in convenience and screen resolution. For me, all the other features are just icing on the cake. I've recently enjoyed the video on the 800 on a long flight, so much that I don't think I'll travel with my Archos anymore.

I'm excited about the upcoming competing high-res devices, like the E90 and various others, but they're still not out yet.
