Anyone that thinks Unix, any version, will ever make it big is a complete idiot. It's been around since the 1960s, and people have been saying since the 70s how it will eventually take over the world.
It hasn't, and it never will. Unix sucks. It's a pain in the backside. I've made a lot of money porting applications from Unix to Windows NT, and that's how it should be.
I'm not a big Microsoft fan, as I still think OS/2 was better, but NT is way better than any Unix variety.
Another thing is, after using shareware, I've become more convinced it's worth what you pay for it. Apache, MySQL, phpBB are horrible compared to real products. The documentation is horrendous, the support dismal, and they are just not as well finished as real products. If you're poor, especially from countries that don't have money, it's worth it. But, for most people here, it's not worth all the problems.
Also, I haven't seen Linux gaining market share, even against Vista, which sucked. Against Windows 7, it's going to be harder. If someone were to come up with something new, maybe they'd have a chance. But, sadly, these idiots just keep coming up with new versions of the failed Unix operating system. If it's failed for 40 years to gain widespread market acceptance, why think it will now that NT is more advanced than ever?
