Mine is 2009 model and I have yet to face this issue. Although my Optical drive died this January and it throws out DVDs when inserted but that is the only problem I have faced so far.
EDIT: Was just stating that 2009 MBPs have no such issues IMHO.

I don't expect to see any kind of lockups or grey-screen, ever. It just shouldn't be part of owning any computer, especially a mac.
