When I first got Tiger, I was very excited. My excitement quickly turned to frustration. Spotlight simply doesn't work. It can't "see" many of my word and excel files, even when I do a search from the very folder the files are in, I come up empty. Apparently, I am not the only one with this problem. I have read about this problem on other forums. I hope Apple fixes it, since its very annoying not to have the same search capabilities that I had in Panther. Also, Tiger breaks Virtual PC 7 (partially), Cisco's VPN client, and Norton Antivirus 9 for Mac. Beware of Tiger if you use these apps. The have not been updated yet.
