Switching from the G1

[advil0]

I'm on a G1 currently and I'm 90% sold on the HD2 I just have 1 or 2 things to work out.

Apps: Are there replacement apps for most apps I use in Android, or even better, can I dual boot android and winmo?

Upgrades: I got my G1 on a 2 year contract Late November 2008, would I be able to swindle the T-Mobile rep into giving me the $200 price tag now even though it's a bit early?

Thanks!
