I sound like I'm on an anti-M$ crusade. Perhaps maybe I am. But I will never buy an OS again. Windows 7 four years ago was the last time.
Linux is the future. Google's Linux distro (a.k.a. Android) is already the most widely used; couple that that with SteamMachines and SteamOS then I would predict (IMO) within 5 to 10 years, you would have a new generation of Linux savvy kids to young adults.
They will determine the future of PC-OS and games machines. The mobile market has already been decided and won by linux.
It is simple for me really, I'll be patient for a year and give AMD that amount of time to get their drivers and Mantle into Linux so I can use it properly. If they fail or show half-hearted effort, then I'll be switching to the green camp at the end of next year.
I will not be alone with such ideas.
The linux boat is sailing in the mobile market already with ARM chips, Intel chips and Nvidia chips; and the game market in the mobile industry is booming! AMD need to ramp up their gears with their software or they will be left behind.
