It does have some nice features and looks prettier but it's buggy as hell. Here's what I've experienced. 1. Hate the default settings. Can't get used to the "natural" scrolling and the default settings in finder. 2. AFP and SMB compatibility issues. Right when you install this you get this rude awakening when you can't login to your NAS drives. Luckily there is a workaround for this stupid problem. http://www.alexanderwilde.com/2011/04/os-x-lion-connection-error-with-afp-and-workaround/ 3. Screensaver randomly starts. Right at the login screen, a random screensaver just starts out of nowhere. When you don't touch the computer for a split second, it could start. Or sometimes, you walk away for 5 minutes, it starts! It's got a mind of it's own!!! Deleting the screensaver plist in the Library directory sort of fixed it. Still acts randmly but not as bad (knock on wood). I remember when I went from Leopard to Snow, it didn't have this many problems!
