I take it back—Apple-haters don't have issues at all.
Good point, and while the PC haters seem less vocal, it's smart to know both platforms.
The simple thing is to get a Mac and add Windows on it. I don't know why so many people are freaked out by the PC/Windows side. Both OSX and Windows 7 have their strong points. One has more stability and the other has market share and it's kind of hard to get a lot of jobs, especially in this recession, if you don't know at least something about MS Windows.
You have all the bases covered that way knowing OS X and Windows.
Also if you have a desktop Mac or laptop as a main computer, I think a PC netbook with Windows is an excellent idea. And if the netbook doesn't work, you can always put OS X on it like a lot of threads here talk about in detail.
It's not like we are talking about a simple to use Mac OS vs. a very terrible Windows 3.1 or Windows 95A anymore. Windows, while less elegant than OS X, gets the job done well enough for the majority of computer users.
