I'd pay for a linux version. (and I signed up just to say that)
I'm a web developer/designer with three desktops (linux,linux,windows) and two laptops (linux,os x) between work & home.
The one machine still encumbered by windows is a family desktop for adobe software and games. The games issue is almost resolved - steam are pushing linux now.
Mac isn't a serious option for me. Hardware at twice the price with restrictions? Haha good one.
