...and installed on my Macbook! Everything seems to be working great, except for ColdFusion 8. Awwww, man. I found out today CF8 has issues with Leopard for some reason. Now I have to wait for a hotfix to deal with it. Other than that, I absolutely love it.
UPDATE: Leopard installed flawlessly in less than an hour. Everything seems to be up and running just fine, except CF8. It is generating an error on startup. However, I've already found a posting online on how to fix this (requires a reinstall), so am still working on this.
Photo booth backdrop effects are cool, but a little flaky--a lot of artifacting going on. I'm guessing this would be better if I used a more neutral background.
UPDATE on photo booth--I haven't proven this yet, but from everything I've read, it's basically just like a "green screen" Hollywood uses. The backdrop needs to be a solid color, something that doesn't match your clothes, hair, skin, etc. and try not to have too much of a shadow of you cast onto the background. I might have to give this a try tonight to confirm.
Other features, such as Spaces and Time Machine, I haven't really tried out too much yet. I hope to get to play with Leopard a lot more over the next few days.
