I've never had a problem with support, or, more commonly, figuring things out on my own. The nice thing is, one can always try a Live DVD of one flavour or another (or many of them), see how it works and if one can live with it, and go from there.
Microsoft's practices annoy me to no end. At least if I don't like a distro's practices, there are things I can do about it, from switching to another distro, to submitting bug reports that don't go beyond some event horizon never to be seen again, to submitting bug fixes, to forking it myself if I were so motivated.
For a person who needs something to "just work," it's hard to beat Linux. Windows has a couple advantages with a couple proprietary software packages, and has tended to have the edge in gaming. When it comes to email, browsing, and general word processing and spreadsheets, operating system is immaterial. Even when it comes down to the nitty gritty of using the operating system, enough is included in Linux as part of the basic utilities to preclude what Windows users accept as paid software.
I don't have crippled archive managers, nor differing tiers of DVD/CD burning tools, nor do I have to tolerate ad ware to back up my system, for instance.
