Nothing that MS do with the latest generation of products (Vista, IE7, Office 2007) really surprises me any more! I am dreading server 2008
I don't have figures to hand, but every new release of OS / Office seems to increase the number of lines of code by a factor of 2 or more, hence more bugs.
This reminds me of the intel floating point debacle with the Pentium 1, way back in 1994! I forget the details, but there was serious concern around the world due to the possibilities of undetected errors in calculations ranging from business modelling and forecasts to academic research and military applications!
Interesting to watch the fall-out, from a safe place! I still use Office XP
