Windows 7 - A Challenge! Me switching FROM OSX -->Win7

At the moment i have a MacBook Pro and a PC with Windows 7 Ultimate.
I have been using mac for a long time, but for MY use i am more and more satisfied with the way that Windows 7 works.
I've been thinking for a while what it takes to make me switch back to windows.
The following things (mentioned below) is the main arguments that i can come up with regarding OSX vs Windows 7:

- Sync between my SE C702 mobile to an Address Book app and a Calendar app in Windows 7 by using Bluetooth (in OSX it is incorporated in the system).
- An app that makes me able to send/receive SMS, and also make/receive calls (in OSX this is done by using BluePhone Elite 2).

If these two is resolved in a manner that is seamless, i will indeed switch.
As i said, this is a challenge for you guys! Let the fanboyforce in you come to my resque (not making fun, but just teasing you FB a little )

Please feel free to send me qualified answers PM/email or otherwise. This is a very serious transition for me .
