Of course this is true.
Macs are not powered by regular components, they use special magical components that never fail under any circumstance.
Software wise (as Spiff said) I can just about believe this as a few years ago as various flash websites would crash my browser (IE and Firefox), however, I have not had a flash crash in some years now - instead it just hogs my CPU at full! (link 1, link 2, link 3.)
Hardware wise, I see a rather large percentage of Macs (in relation to other brands) in for repair - usually down to hard drive related problems. They do crash, and they crash often.
