Your rant, while containing an element of truth, is basically agreeing with the windows developer who wrote "Why Windows development falls behind." He said that windows falls behind due to various factors that make it hard to improve existing functions. You said Windows is better because it doesn't change as fast as Linux. You cant have it both ways.

I use and write code on all 3 major OS's (win, mac, linux) both at home and professionally. Each has it's strengths and weaknesses. Windows changes the least. Linux changes the most. Mac is in between. You prefer slow change because it reduces your support burden. For someone supporting average consumers who use PC's for web, mail, facebook and chat, that's a reasonable position.

It is however, not the only viewpoint. Windows has and probably will remain dominant on x86 desktops because most users are like your customers. But have you noticed that whenever a new area opens up (supercomputers, tablets, phones, whatever) Windows fails hard. That's the fast changes helping.

1% = 421,650 This is why you think it's failing.

Math fail. 15 terawatts = 15,000 gigawatts. So, to provide half of 15 terawatts, 7,500 fission reactors would be required. But what's a factor of 133,333 anyway.
