Two (related) questions for you guys on MBP Revisions: 1) What conditions have to be met to be able to say that a new hardware Revision is out? The Macrumors MBP Guide says the latest revision of the MBP is Revision F - the Unibody design announced in October 2008. So does the latest round of MBP upgrades from the beginning of March constitute a change in Revision, and we're now on Revision G? Or is that yet to come? 2) Did the March 3 upgrades to the MBP address any other hardware issues? I'm not thinking of anything specific, just curious to know whether Apple simply upgraded the processor and offered new options, or gave the whole machine a once-over. If it's the former, doesn't that contradict the 'always buy the second revision of a new product' logic?
