I'm still using Windows XP at home.
One of the few smart men here on Geekhack . The poor bastards at Redmond is quickly shoving Windows 8 into it's crypt faster than Vista, goes to show how confident they were for it's longevity in the world of Computers ) .
As it stands now, WINDOWS 7 and Windows XP will be used by business for many decades to come simply because of Microsoft's complete stupidity in publishing and selling the current monstrosity, pretending to be an OS of some sort. Very glad to see them setting them selves for a major fall in the coming years when it comes to profits and share holding within the business community.
I always wanted to see Microsoft shaft itself in such a way that it will most probably be splintered off in small chunks for sale, but who would waste valuable money buying into Redmond's current failures within key business services and products ?
Windos XP came out in October of 20001.
Windows Vista came out in January of 2007.
Windows 7 came out in October of 2009.
Windows 8 came out in October of 2012.
Windows 10 is scheduled for "late" next year.
So, that's just a little over five years between XP and Vista. Just about three years between Vista and 7. Another three between 7 and 8. And now it's going to be just about three years between 8 and 10. Your logic isn't too good.
Any halfway intelligent business is dumping XP as fast as it can. The company I work for shut down the final few Windows XP machines when I started with them last year. It's a major security blight for any company that hasn't elected to finally move on from an OS that is old enough to like the Twilight series. And while I'll admit that Windows 8 server products are pretty odd for including the "Modern" user interface in lieu of something more business styled, it's really odd that a business would purposely lag behind in terms of technology because of a UI hiccup. And that's all it really is. At the end of the day, if you're not smart enough to find your way out of the Modern UI to the desktop... well, I don't know. There isn't a good phrase for that.
Either way, those praying for Microsoft to fail will continue to hold their breaths. Windows 10 will be reluctantly adopted by many, people will ***** that it's not like Windows XP, and the rest of us will use it because it's probably going to be a fine operating system, iteratively better, just like every other OS released in the last decade or two.
Or you could buy a Mac or evangelize Linux. Whatever.
