One guess...
My guess would be that whatever he teaches, it's done on a Mac, because the comments have a smell of rotten Apples, and about as much credibility as the Apple commercials. Monkeysoft? Wait a few months/years to install SP3? Monkeysoft's latest attempt? Phew.
I mean, Vista isn't my favorite, but it works OK, just a bit demanding, and MS's service packs and updates have been remarkably good the last few years...I had no issues with multiple machines for XP sp1, 2, and now I've put SP3 on 4 (so far) without a hitch.
I read the precautions MS gave; I didn't see any confusing red warning lines, just a bit of common sense. I covered myself with full disk images of each because that's how I do it, none were needed.
