Hmm... let me think... when was the last time Linux failed on me...
Oh noes! I can't think of one! :p
However, I can say that one time, Maya crashed on my XP box and Windows decided to be helpful and create a crash report with a crash dump (a file that contains the contents of the memory at the time of the crash to help Bill fix his OS), which actually caused Windows to crash again. The help was more dangerous than Maya crashing. That's Windows for you!
C. P. U. Its not a big processor... Its a series of pipes!
