After messing with various 2.1 ROMs for the last week or so, I can honestly say that i am thrilled with the decision to not include the 2.1 Launcher on the Droid.
--Its slower than the drawer, and less intuitive.
--Its annoying. After launching it about three times and watching the icons fly into view, I could care less. I have to wait for that crap then scroll a screen at a time to get what I want. Which I might add, is less precise than the drawer.
I do like Live wallpapers, but the 2.1 Launcher is only needed to interact with them, and imo, interacting with them is also dumb.
So, the only thing I hope is they include the extra home screens that the 2.1 Launcher has. We know it can be done easily and without issue, so here is to hoping.
