i do not agree. I don't know of any better mobile browsing device than the n800. So I think the price is ok for such a revolutionary device.
Opera on n800 is better than the nokia webbrowser for the n95, and also way better than any brower for windows mobile or palm, or gaming systen (psp for example)
Only the umpc devices have better webbrowsers, but they are more expensive and larger or a lot heavier.

I also think that the user interface of the s60 phones, like the n95, has a lot of problems, and in general I don't think it is superior to much of the Internettablet UI.

The only mobile device that i think may compare to the web experience on the n800 is the apple iphone (but with very different strong points). But we will have to see if it lives up to expectation. (The screen is rather small, and i seriously have my doubts about the touchscreen keyboard.)
