Random Macbook Shutdown

I cannot in good conscience recommend my Macbook anymore, much as I’m in love with its features and ease of use. Apparently the “random shutdown” syndrome that I experienced has been pretty much experienced by many around the world - the worrying thing is reading some of the comments on Ubergeek it seems having the logic board replaced (as my computer is doing right now) may not prevent a recurrence of the problem. And the fact that Apple is only issuing a terse response is pretty crap.
