Dealbreaker apps for Windows 8

I have been a Mac user for years now, but I'm almost ready to make the switch. I'm non-plused about Mountain Lion, and Windows 8 positively blows me away.

I just need to see some essential apps supported before I take the plunge:

  • iTunes - I've purchased too much video content through the iTunes store to have to start over. Plus, I think a Metro UI iTunes would look pretty slick (think cover-flow)
  • Chrome - It's my default browser and has been since it came out.
  • Some type of Simplenote client
  • A great programming/text editor - think about working on a coding project and having a video chat client docked to the side for real-time collaboration.

What are some other ones?
