Yes, it's very cool. Freetrack has made PC flight simming a completely different world for me. Once I've recovered from my recent splurges (an orgy of wii, wii hacking, new flight controls, IR model-building, batteries, refreshments, etc) I'll be making a donation to FreeTrack. I wouldn't have been having all this fun now if there were no FT.
It's also fun being pioneers with FreeTrack. A few years from now, when all sorts of biometrics become ubiquitous, we'll be able to look back and remember how we were wowed, and got inside these virtual worlds before most people knew what was going on.
THANKS FREETRACK!!

Someone should make a whole set of Scully emoticons.
