I just saw a video of quake 2 running on the n800 on Youtube. You can see it yourself here:

It appears to be running at quite decent FPS. I would love to get my Quake on with the n800, but games like this are really only enjoyable with a mouse. Has anyone explored getting a bluetooth mouse working with the n800? There are many applications which would benefit from mouse support. There are some really nifty TINY bluetooth mice, too. Combine that with my bluetooth keyboard and you have the most mobile desktop on earth.
