Well, I love the way HTC customized android and it is very similar to their customizations with all their Windows Mobile with Manila 3D.
I love the name Sense UI for the Android customization. Smooth, flowing interface. They are also trying to achieve this sense feel on their winmo devices but I think Android is way better BUT I have yet to try it out myself, if I can get the chance to!
The question really is, aps, well this should have all the basics that we need but to those heavy users out there, they will be looking for aps and since Android is open source, I think it should just be around the corner.
