What I dont get is people who like "computers" but not a particular flavour of OS (or even CPU).
Reasons include the "It could have been a contender" complaint, whereby another OS, often Windows is decried for it's dominant position, it can be because the OS is difficult to repair or install such as Linux or that the user feels the cost of entry is too high as in the case of OSX, for instance.
There's more than a few on these boards who will denounce Windows, Linux, OSX... whatever... till they're blue in the face and then brag about how they've never used them.
Again, in the above examples that is covered to an extent, although I agree in part with what you're saying.
