I use Open Home. It works beautifully, but only if I don't use any skin other than the Android default. If I use the Open Home default it crashes occasionally. If I download additional skins, it crashes no matter what skin I use?!?!
I'm happy with the default Android Skin and ejoy the added home screens a quick access to fundamental applications. Open home uses are sort of quick access icon drawer that you can open up on any screen. Works well and helps to keep the clutter down.
