What about DirectX though?
That's the reason all the games I've heard of being ported to Mac and Linux are based on OpenGL.
I don't think DirectX games even run very well in WINE, though there may be a way...
Just out of curiosity - do you see many such people where you are?
I'm a big FOSS advocate and long time Linux user. But even so, I'm not so anxious to jump ship as I am about knowing there will be a place to jump to if it ever comes to that. And most of the savvy-NIXers I know are in the same boat. Our attitude is: Why pick when you can mix & match the best from both?
I'm running about 50% open and 50% Windows right now. (I was closer to 80% Linux prior to Win7.) So I see the future of Linux more in terms of being "co-adopted" rather than becoming a replacement for Windows. And I believe that will be the case as long as copies of Windows remain available.
Personally, I run Linux 100% at home because it simply fills all my needs.
The only reason I would have for running Windows is out of curiosity, which may happen this summer when I plan on buying a new laptop.
That said, I totally agree that multi-boot or virtual machine setups are a good enough solution for many folks who are either curious about Linux, or see the benefits of running Linux applications in a native environment rather than a sketchy port.
Like you said, "why pick one when you can mix & match?"
THAT segment is here already, no need to worry about them, they're doing fine.
To answer your question, I have seen this particular sentiment on various forums, tech article replies, etc. enough times to conclude that a fairly large contingent of people WOULD completely jump ship (for philosophical and/or technical reasons mostly), but the gaming aspect is one of the roadblocks, and a major one at that.
It usually goes something like:
"I would totally dump Winbloze if Linux ran [insert game here]/had [insert software here]/supported [insert hardware here]"
A major player in the Games market making a concerted effort to bring commercial games to the Linux platform eliminates (or greatly reduces) at least one of those hurdles, and with the gaming industry making more money than Hollywood
, this has a potential to be BIG.
No, the Windows barge won't be sailing for the coast anytime soon, but for those itching to mutiny, Linux will have a lot more bath toys pretty soon...
