You are right, I really don't understand what all the fuss is about. New versions of software come out all the time, my company has 3 different versions of oracle and we have to use all 3 because of different applications.
Say thanks to MS that they didn't ask you $50 for the patch.
All it takes is 1 co-op student to package the patch in 1 day, 7 days for testing and change requests, 2 days to deploy patch to 5000 PCs. How hard was that? And that it using SMS (slow moving software).
