But, as is rightly pointed out, many people have no need for any special features and are not making risk assessments when buying a home / small office machine.
That issue is also a factor of price.
For instance, if I spend $800 on a laptop I get all picky about performance, specs, warranties, etc. However, $300 or less on a netbook or cheapo tablet and I treat it more like a disposable lighter, if it breaks I'll just replace it, extended warranty isn't worth it unless you buy somewhere like Costco where the 2nd year is included in the price.
But looking at all my devices, only 2 are Windows, the rest are Android and Linux, 3/5 of my computing time is spent outside of Windows and I don't even notice as I can do everything I need to do in just about any of the environments without breaking a sweat thinking twice about which machine I'm using.
Today things are more task oriented than in the past where the OS was more obvious as you plopped down at the keyboard to be greeted with with the old "C:" prompt. Which icon you click on to bring up a spreadsheet is pretty much irrelevant which OS it's running on as long as that spreadsheet or document loads, you can do your work, and save the results.
More importantly, so many people do the majority of their work in a browser using spreadsheets and documents on the cloud, that you're using the same exact interface no matter where you are on any OS or any browser, which is why I'm say MS is really losing it's grip.
Not sure how successful MS's attempts to reclaim their online throne with OfficeLive, or whatever it's called this week, have been, but making it more dependent on MSIE is probably their best strategy to keep people locked into MS products, much like Google Docs work best or only with Chrome type of situation.
