So far from mine, there are subtle differences, mine is a DVT stage prototype, so everything is all working, ready to be released. Since it was built in August of 05', I believe that the computer was used by software companies to perfect apps for the Quad core. So far, there have been a few bugs that I have noticed, like not waking from sleep properly, and no going to sleep properly. Most of these issues may be due to the PRAM being old, but who knows!!!!
Yeah I agree... It was possibly used by companies such as Adobe, etc. Sounds great.
