Very nice.
-4 spots to put shortcuts across the bottom bar
-app drawer is replaced with a NexusOne-esque launcher icon.
-supports interactive live wallpapers.
-supports from 1 to 7 screens.
VERY NICE. I can't recommend enough. Been using it for a couple days now with no force closes.
EDIT: Apparently it does cause issues with non-rooted phones as it shares an id with the default launcher app and changing to 5 or 7 screens creates an issue as it modifies the data file that both use. This creates force closes and issues with Astro.
