It's a really good start, a few suggestions:
1 - Ability to change the background
2 - A few icons for programs show up HUGE, like EasyMoney and SetCPU, it'd be more aethetically pleasing if they were all the same size.
3 - Preference to change the trigger to long press on Home (or any HW button for that matter). I use Voice Search alot on my N1, having to use the Complete Using dialog or losing Voice Search kills the joy a little bit.
