Certainly! Apple's closed system allows them to force upgrades. Microsoft has no such luxury! At work we are finally moving from XP to 7 later this year, and even then it is with reluctance. I still run a Windows 2000 virtual machine for some old programs for which reinstalling would be messy or perhaps impossible. And there is incredible backlash against Windows 8 and 7 is still readily available for purchase even on new machines.
True enough. However, a lot of negativity about Windows 8 seems to be down to unfamiliarity & some ignorance. FWIW, I've only used it for a few weeks. Its biggest initial drawback, the Metro interface on non-touch screens, actually has an easy enough workaround to revert back to a Windows 7 type start screen. Windows 8 Blue, out later this year (essentially a W8 SP1), should fix such issues. Overall though, W8 maintains excellent BC, boots faster, makes better use of hardware, etc. IMHO, it's a fine OS.
That said, I much prefer OS X. I do most of my serious work on my Mac because, generally, I tend to do things faster. But I think as time goes by, any "
incredible backlash" against W8 will subside significantly.
Keep in mind that many PC users still even hate Windows 7 & swear that they'll stick with XP for as long as its feasible to do so.
Fact is, many people simply don't like change. Particularly if it means abandoning computer interfaces that they're long familiar with.
