Since I'm a fairly new user to the Mac altogether, I think it's quite understandable that I really like the new features that Tiger brings with it. For me a good thing is Spotlight. Dashboard wasn't necessary, however, it's a nice add on. I also like the Burn Folders. Just drop something in there, and press burn. Smooth! I didn't get behind this Smart Folder thing yet, but I'm sure that if I figure it out it might help me. The Automator is good for me because I still have some 100 pictures left that I need to turn. I don't want to do that manually... What else? Ah yeah, speed. I have noticed some improvement on speed compared to Panther. It's not THAT big deal, but it's noticeable. I was also able to import Mails from Thunderbird into Mail 2. Worked quite seamlessly. But the Mail GUI is a bit different than what I know, but it's good enough for me. Well and games? UT 2004 runs good. No problems with it, also the other games I have, like Neverwinter Nights and Dungeon Siege also run good.
Well, I'd give Tiger a rating of 9/10, it's pretty good. I'm curious what the next features in 10.5 are gonna be.
