Frankly with all the whining about Vista I really don't have an issue with it... other than that EVERY DAMNED APPLICATION I access needs to ask permission to operate...
I ran Win7-Pro for about a month on one of my notebooks and really didn't see any significant difference
between Win7-Pro and Vista-Buisness(which I reverted to)
Would it be a brilliant strategy for them to have done so? Yep, certainly...
Which is why I don't think it was intentional, I don't believe they were that smart.
I have long followed the dictim that when malice and/or conspiracy are possible incompetence and/or stupidity are much more likely.
