So Teksoft release a new "shell replacement" software today called Skybox.
I tried for about 10 min and didn't like it. Not to mention, its pretty much a ripoff of the Spb Mobile Shell concept with things like an "InfoScreen" (a la Now Screen) and the menu is nearly identical to the Mobile Shell 1.0 menu.
But maybe some folks will like it.
