I've been working on a Facebook application with a client for a few weeks now. We just released it to the masses and I think some of you might be interested in it...
It lets you list the computers you own, browse your friends' computers and comment on them. It's called "My PCs" and you can add it here:

If you don't want to add the application you can still browse your friends' PCs (which is a nice change for a Facebook application):

Feel free to hit me with feedback! New features are coming down the pipe, like leader boards to see who has the most RAM and hard disk space.
