I just saw Jon Udell's article about the Sun's white-box Linux desktop and while Jon was talking specifically about what sounds like more confusion from Sun, it got me thinking about what it would take to move to Mac / OSX. My short list of apps that I actually use at home:

1. Quicken has to work. Just checked, that's available
2. Some sort of office package. There's good old MS Office, but that price tag! I've been using StarOffice at home, but there's no OSX version. Mac's already expensive, add ~$400 for Office, and I could buy a really nice wintel machine.
3. A JDK
4. Radio
5. A good code / XML editor.
6. I'd like to have .NET/Rotor/Mono available, but last I checked, there's no OSX port.
