In 1 - 2 years from now I bet you will be able to use Photoshop and Adobe Illustrator in the cloud only (not necessarily a good thing). Your OS will be irrelevant (in the sense that any of the above apps will run on any OS that has a browser).
Totally agreed; I checked out the ultra Photoshop web app just the other day.
Until it happens though, I'm stuck with either the hideous VMWare window chrome or cursing at Gimp/Inkscape for not having the features I've been used to for years.
P.S. someone make a real PS & AI replacement for Linux and/or Adobe port CC, so I don't have to use Mavericks in a VM anymore
