This is all BULLSHIT, who wrote this? Steve Jobs?
I administer as the Dir of IT, over 18,000 PC and a few Macs (that's all that are left) at a major school district in California. We have seen ZERO problems after the update, NONE on Windows XP, 2003 or Vista PC's ! I think those numbers (over 18,000) versus the paltry number this stories so-called "journalist" reporter quotes speaks for it's self ..... this story is BULLSHIT.
Frankly, I see this as a anti MS story plant by Apple PR or by an Mac zealot media writer.
With the few Macs we have left after YEARS of bugs, flaws, prematurely dead Logic Boards amongst other costly hardware failures, we have MORE problems after nearly every Apple OS X update that we ever have with our 18,000 plus Windows boxes.
You know what we call Macs? Just another PC Clone, but with a much more flaky OS at twice the price of a Win PC.
