Photographer/web design - recent switcher.
The quick view and cover view features are cool, also the new sidebar in Finder, but that's about it. I don't think it's worth the money just for that. I've also had a lot of trouble since installing it with things just not working right. So far I've fixed them all, except one problem, but stuff just keeps coming up. Also, it has a few "upgrades" that I don't like, for example, the new search. When you search for something in a finder window on Tiger, it sorts whatever you searched for by File Type, and only shows the top 5 of each file. You can choose to show more of a certain file type if you want. Now with Leopard, it just shows a list. A plain boring list, just like windows. I really liked it the Tiger way better. Unless that's a setting you can change on Leopard that I'm unware of? I wish... 🙂
ETA: Also, I didn't think it was possible, but Preview sucks even more than it did before. I hated the fact that before, I couldn't just click on one image in a folder, and then use back and forward arrows to browse through *all* the pics in that folder. Well, you still can't in Leopard. But now you can't resize the pictures easily either. Before, all you had to do was resize the preview window, and it automatically adjusted the size of the image. Now when you do that, it just makes the window smaller, not the image, causing scroll bars. You can use zoom in and out buttons to make the image smaller, but they do a lousy job of zooming and the images get very blurry and practically unrecognizable.
