Leopard (Mac OS X 10.5) is installed

Some of my favorite things thus far:

- The Finder finally has a hot-key sequence to rearrange files by name in a folder. Ctrl + Command + 1 does the trick. Hallelujah! That's one of my most-used Finder features.

- Screen Sharing will be an incredibly useful tool for supporting other Mac users I know. How many times have I had to try to walk someone blindly through setting up something over the phone. Screenshots over iChat just aren't the same as having control to make fixes. Windows has had Remote Assistance for how many years now? It's about time, Apple!

- UNIX '03 certification. Nobody but me cares about this. But, it really is a great thing to have, especially for Apple's computers to become more acceptable to enterprise customers. I can use my UNIX software with a guaranteed simple re-compile on my Mac now.

- Xcode 3.0, Interface Builder 3.0, Xray, etc. They look like an incredible set of new development tools. I can't wait to dive in.

- Stacks are incredible. What a great feature. I've always kept my downloads in a separate folder, but it's great that that's now the system default. Stacks are a great way to see your most recent downloads.

- Quick Look and Finder application-aware document thumbnails -- finally a way to visually sort through and find what you're looking for quickly in the Finder windows.

- Console lines are separated by alternating white and blue lines. Makes reading the console logs so much easier.

- Terminal tabbed windows. I can finally have multiple Terminal sessions open in just one window. Saves lots of desktop space.

- Spaces will be great for separating out windows by task. I've used virtual desktops for years in UNIX.

Can't wait to dig into the rest. This is definitely my favorite upgrade since Panther.
