I installed Longhorn yesterday after I downloaded it off of MSDN. I took some screenshots, the OS is really buggy and too XPish but isn't THAT bad (as in it has a few new features) the networking didn't work and I got an error whenever I tried to install my linksys router software. The unminimize from system tray doesn't work right, it takes about ten minutes to shut down and such. I don't like the tray and stuff being on the side either. Basically, it's a more buggy/laggy version of XP at this point (pre-alpha).
