Wow that sounds odd. I've got an i5 retina iMac and it just flies. No stability issues at all. If the problems you're seeing were more widespread it would be all over the press, must be something to do with as you said, 'the shit you put on them'!
My thought @M_V, don't be put off an 27" i5 iMac by the above story, buy a MacBook if you want portability, or the iMac if not.
