I have had Macs crash on me, several times actually. I got rid of my iMac and now just have a the white laptop mac (whatever they are called in mac marketing jargon) I like it, it does the job, but prefer my PC for real work.
I bought it so the mrs would use it since she isnt the most technical person, and "macs are so easy to use and just work yada yada mac rhetoric"
She hated the thing and uses my pc hence I inherited the mac. There are somethings that mac does better than PC's, I hate them more as a company than the computers they make.
