The next major release of Mac OS X - Leopard, was previewed today at WWDC. Here are my first reactions:

- Time Machine. This will change backup forever. And for all those times you've misplaced or deleted things, this is going to be perfect. Terrible icon.
- Spaces. Honestly, I'm not impressed with the idea, never have been. However, if its easy enough to set up, I may use it. Terrible icon.
- iChat. Well, isn't iChat just becoming awesome. Especially cool is screen sharing, which looks like a "lite" version of Apple Remote Desktop. I'm not sure what happened to the GUI, though.
- Mail. "If you're anything like me, you're constantly emailing yourself notes." Uhh, what? Other than that, looks great, and finally puts a solid end to RSS readers.
- Core Animation. Looks amazing and I can't wait to try it out.

Still to come in Leopard (hopefully): updated system theme, resolution independence. ;)
