That's because they don't use OS X. No service pack has ever made the kind of changes an OS X upgrade has, period. Anyone who spends time in both operating systems knows that's a ridiculous sentiment only spouted by the most ignorant users. I've also never heard it from someone who has ever actually used OS X for any real length of time. Ignorant OS X users tend to consider Windows upgrades overpriced. That's not true either. It's just a different release strategy. Microsoft can't work on that kind of incremental release schedule without upsetting enterprise customers. The only real difference is Apple has stuck with the original OS X UI and chosen to refine it, whereas Microsoft throws out the old skin for every release and designs a new one which makes updates seem more drastic. That's just the UI though. Behind the scenes, OS X has made as much progress between 10.0 and 10.8 as Windows has between XP and 8.
