Another neat thing about virtual machines is, you can have two, three, many virtual machines on the same Mac. All they take up is disk space (and RAM, but only when they're running). You could put your TurboTax and other sensitve stuff in one VM and keep all the rest in another and only start up the TurboTax machine when you actually need it.
And, I'm pretty sure TurboTax exists for the Mac, anyway, so maybe converting to Mac native is the way to go.
I want to keep using my notes in MY Documents on FR with political and religious responses.
Stuff like that is probably a prime candidate for conversion to Mac native, depending on what you've been using to keep your notes.
Most of the notes are on Notepad or Word.
