No, its that PC users are tired of mac users lying about their systems working perfectly to try and show intellectual or class superiority -- or some such thing. And, to a lesser extent, irritation at the emotional attachment most mac users seem to have to their machines such that they get terribly defensive when anyone suggests that anything made by Apple isn't the best.
But, 1L, they are not lying. Most Mac users are reporting their experiences truthfully. It is YOUR unfounded assumption that we are lying.
You state later in this thread that you have owned Apple products in the past such as an Apple II and you now own an iPod... but do you own an OS X Mac? I doubt it. If my doubt is true, then you have very little experience with modern Macs on which to base your opinions.
I on the other hand, in addition to owning several OS X Macs, own several Windows machines running Windows from 98 through ME, 2000, XP, and XP Pro. I maintain the computers, IT security, and networks of about 35 small businesses, some of which use Macs and others that use Windows. I submit my experience on both systems is greater than yours.
Many Mac users have come from the Windows environment... and again have experience on both platforms. The same is usually not true of Windows users in general who tend to spout what they have heard from other as ignorant of Macs as themselves.
