We use TMobile to connect via our bluetooth enabled cell phones. Works fine.

Safari works great also.

There are some books on switching to the Mac that you might want to look at.

Also, for transferring your files from the Windows computer to the Mac, consider getting a product called Move2Mac. It has gotten good reviews.

I think you'll find that your need for virtual PC should be minimal. A lot of folks switching think that they'll rely on it a lot, but really, either the same application or a better equivalent can be found that runs natively the Mac 90% of the time.

Another thing that you've already experienced is that support people will often immediately jump to the conclusion that their products don't work on a Mac, just because there aren't many Mac users out there using them and fewer of them need to phone up support for assistance with them. The truth is that you will rarely encounter an incompatibility issue with a Mac these days. Anything a Windows or Linux machine does a Mac does in pretty much the same way (or easier).
