Brewman; yes
"would a Linux user say the same"
Yes. "Linux users" are normal people and would pay money for software provided it's benefits over competitive alternatives justified the price difference. For example, when Adobe tried to sell a Linux native Photoshop it flopped; the price asked for Photoshop did not justify the few things that alternative software didn't do.
For me personally, I'd have dropped money for VMware Workstation if VMware delivered it for Debian 6 (Debian is not obscure enough for third parties to ignore supporting). I'd also drop money on games if they shipped with a *nix native install. Having to stop everything I'm doing and reboot to Windows is the primary reason I do far less gaming now. I have time to pop open a game if it'll leave the rest of my *nix stuff chugging away but the game developers don't seem to have any interest in my money.
The difference between a "Linux User" and "Windows User" (used in the most generalized of meanings) is not if they will purchase software or not. The *nix user simply has a larger choice of already available software with which retail software can't or chooses not to compete with.
