Microsoft really nailed it with Windows 7. 400 million happy satisfied customers can't be wrong.
Did they really nail it? Nail what? Quality and Universal Licensing are often mutually exclusive terms.
Yes, those customers
can be wrong. Ignorance, or nonchalance, or
inability to afford a Mac. This last point was highlighted beautifully by MS' flat-footed Laptop Hunters ad campaign.
Why the do you think Windows sells? It comes with every PC known to mankind. And you can join in for only a few hundred bucks, if that.
Bargain Bin Ballmer selling PCs loaded with Windows on the cheap. Every PC under the sun comes loaded with Windows. Shocking.
Microsoft licenses their OS universally. Apple does not.
I should hope MS sold record numbers of Windows 7!!
It's hundreds of millions of PC users waiting for the Vista nightmare to be over. What did you expect? Poor sales of Windows 7?? What are the alternatives offered by MS? XP and Vista. One is a 9+ year old dog of an OS, the other is a massive flop. That's hundreds of millions of PC users dying for an upgrade after years of getting the shaft. And Apple's Premium end of the market has natural barriers to entry, starting with the $1000 minimum fee. Apple doesn't compete in the market segments occupied mostly by MS. Of course, Apple is now transitioning away from the traditional desktop computer + desktop OS paradigm.
PC users outnumber all others, and always have, whether MS released a good OS or a lousy one - PCs are cheap and now more disposable than ever (netbooks - if they even matter at this point.)
The bottom of the retail pyramid is always the widest. The biggest computer-using segment uses PCs. Now throw in an OS that fixes Vista and by sheer force of numbers alone (volume) you'll sell in vast quantities.
There's nothing special here. Just the massive number of PC users who suffered for years, who have jumped at the chance to upgrade. It's nothing new, miraculous or groundbreaking.
It makes no difference whether Windows succeeds or fails (though we're seeing signs of a shift, thanks to what we're getting in the Post-PC era.) PC users, by virtue of the low cost of entry into the PC market alone, will always outnumber users of all other platforms. Windows will always sell well, in whatever form, because it can run on the cheapest hardware - and this is what you find the most of. But now, we're seeing highly concentrated sales of a particular version (good news) because everyone was waiting to upgrade and end the XP/Vista pain, which lasted far, far too long.
Apple doesn't whore out OS X to every hardware maker, and the entry-fee starts at around $1000, not counting the Mini. Apple owns the Premium end, and posts record quarterly sales (in a recession) as well as record YOY sales. Now
THOSE figures are impressive, especially when consumers have cheaper options. Never mind Windows that ships with everything, especially whatever's infesting the bottom of the market.
Current realities are a bit different, however:

You can either look at "400 million users" and assume everything is rosy, or you can look at it critically and realize what's behind those numbers and what they mean.
