Upon further review I want to make another post, this time directly addressing Microsoft's warnings about Linux:
Camera, iPod, mp3 compatibility
Printers and scanners compatibility
You can connect pretty much any make or model of the above named devices to a Windows machine and have it working either out-of-the-box or after a driver installation. You can usually rely on name-brand, popular devices to work in Linux with minimal tinkering, although some things can often be a pain. There are multitudes of exotic and obscure devices which won't run under Linux, usually ones with required proprietary drivers which are only supplied for Windows machines. I'd say "Few" is a correct estimation by Microsoft, although that "Few" that are supported under Linux do happen to be the most popular and highest-quality devices.
If their customers want to plug in any mp3 player they find at their local flea market, they want windows.
Software compatibility
Here Microsoft rated Linux "Limited," and for a good reason. Windows has more applications developed for it unit-per-unit than Linux does by far. While fewer, the applications developed for Linux tend to get done most any job that needs to get done and there always seems to be 2-8 alternative apps for any given task (LOL). Windows might have more university textbook software, malware, and Free AOL Trials developed for it, but Linux has it where it counts.
If their customers want to run the majority of bargain-bin softwares and binaries they can find over the whole internet, they want Windows.
Windows Live Essentials
Uhhhh... OK. They're not lying, you sure can't get Microsoft-branded services on Linux (not natively anyway)... if their customers want these services they should purchase Windows.
The games your customers want
It's true. Their customers want a lot of games that are only decently supported by Windows. If their customers are gamers they need Windows.
Authorized support
What's that, like, paying money to call tech support and listen to someone in a foreign country read the contents of the Help files already on your machine back to you? If that's what you want, you need Windows.
Video chat on all major IM networks
You might think it's trivial, and so do I, but this is unique to Windows.
In the end there aren't really any lies, no half-truths, and no exaggerations too ridiculous. The features they offer just aren't appealing to our type. We've got different ways of doing things and simply do not require their services. They've designed their business model to cater to the everyman computer customer. We're just not part of their target market.
