Nokia N800 as Firefox Computer?

Toni Schneider, CEO of Automattic, like many of us, can do much of his digital work and play in his browser.

my digital day is currently spent in the following apps: WordPress, Yahoo Mail, Bloglines, 30boxes and Google. And they all run perfectly well in Firefox… I want a Firefox computer. A nice, sleek, solid state notebook with a big screen that you open up and it just runs Firefox. I bet this could be had for a reasonable price, it could have a nice long battery life and start up almost instantly.

I feel the same way, although I’d be inclined to go for the portability of the Nokia N800. But will Firefox be ported to it? Could I learn to live with (or should that be in?) Opera?
