Even though it's been done a bunch it's still really fun to play OS spoofs. This one was particularly awesome becuase of the graphics and sound, the only thing was that there wasnt much to do. Maybe you want to add more to it? Make it a little bigger? That's the only thing I can think of.
Oh yeah, i'm a WXP user, i personally like that OS (except for it's hellish compatability) but I still found this great. Good luck in the portal!
