It sounded like, Prophet was saying that as a *main* browsing device, the size is not ideal. I agree with that, and I wouldn't want to use my n800 as my main browsing device. But, the screen is just fine for browsing on the go, and playing things like SuperTux (though the controls are not fine for playing supertux).
Even my OQO with the 5" screen and much higher resolution, it was too constricting to use for extended periods. Again, these screens were great for on the go type stuff, but not for a main device. I also think the 7" EEE screen is too small. That's why my MacBook Air is perfect, nice big screen, still lighter and slimmer than an EEE, and way more powerful.
