Interesting story... but Metro was first used in Encarta 95, and the old MSN. Over time they started to use it more and more. Like Windows XP Media Center Edition has a metro design, the Zune...
A lot of companies follow MS's design trend... Remember in 2007 when Vista was as glassy and chrome covered as an OS could be. Programs, websites, advertisements, and graphics in general followed the same thing. Now they are doing the same thing with Windows 8.
Either way, MS is just combating Apple. People were complaining that MS was not revolutionary and the same old. All of a sudden, now that Windows is different and is new, people are whining that they want Windows 7 back. Listen people, change just is a
fact of life, and you originally wanted it too. I get that people want backwards compatibility... but seriously... sometimes you just have to move on and learn something new.
And you really think that Microsoft does not have a reasonable support lifetime? Apple deems their 4-year iPad to be as good as garbage. My 6-year old laptop runs Windows 7, and will be supported until 2021, and software and security for it will be around
for a long time.
