1. Well I'm fairly satisfied with the latest Windows Mobile 6.5.3 (or 6.6, whatever you want to call it) builds, as long there's HTC Sense included, but I am indeed waiting impatiently for Windows Mobile 7.
2. I don't know (although it would be for me), but I think HP is the only company that doesn't do any skinning (except for a few stock apps). But, HP only sells one Windows Mobile 6.5 device on one carrier(in the US, that is), and I'm not even sure how many countries it's sold in.
3. I have thought of moving to Android, and, actually, I'm still not sure which platform I should stick with. But, if I were to leave Windows Mobile I would definitely go to Android.
4. I like its great multitasking capabilities(that's more of an opinion), its built-in file manager, its complete Windows Live support, its many browsers which ,collectively, can do anything a desktop could (although not all at once), and its partial Zune support.
5. I call the software Windows Mobile and the devices Windows phones.
