Yeah. I noticed the Finder and UI changes and quite liked them. I don't use OSX enough to even touch on the other upgrades.

I use Linux for servers and Windows for workstations. OSX would be nice for servers but I don't really need the fancy Apple GUI.

The Apple Xserve also looks really nice for server gear but is just added expense. This is because most of the time the servers will be sitting in a rack somewhere and I don't really need to stare at the front too much
