If I can add, if you bought a PC back in 2009 or 2010, chances are that it's still running 7 just fine unlike vista. If you bought a vista PC, ESPECIALLY a laptop, by the third month it was like dragging a dead dog. Most people aren't actively looking to upgrade to 8 over 7 just yet.
Then there is the fact that when vista and even 7 came out, economic crisis wasn't a weekly used term. People don't look into buying new PCs every two or three years like they do with smartphones or even tablets. They last for a good five years if it has 4 gigs of RAM and a 64 bit processor. I have a friend that has a laptop from like 2007 or 2008 that has gone through vista, 7, and now 8. Why? Four gigs of RAM and a 64 bit processor. If I should say, I'd MUCH rather see OEMs focus on really good build quality versus pumping out fifteen models per year. It's like what Nokia is doing with their Lumia Windows Phones, they're focusing on lower end very nicely built Windows Phones, and tiering them into different price ranges and hardware features. That's just ONE series of Windows Phone they have, unlike HTC where they have the One, One X, 8X, 8S, Titan, and many many others they have.
And yes, Windows 8 does get a bad rap by some, usually those that really haven't taken time to thoroughly explore the OS to have a valid opinion about it. And, yes there are flaws in it. I want 50/50 app snap versus 33/66. Thankfully though, Windows 8 is making Microsoft change their ways and update their products quicker, probably like they would had when xp came out, they would had released vista two years after it after xp came out a year past 2000/ME. But this is a long haul OS, a pretty big UI change doesn't get adopted overnight and it's rather foolish to think that happens. It doesn't. At all.
By the way, I'd look at Nokia's stock as well. That really has nowhere to go but up.
