As of July 24, most recent release info here. As of Nov 15, most recent release info here. Everyone loves a good laptop update, but the Penryn processors in the most recent updates are the same CPUs we had almost a year ago. As much as I love the new MBP design, I'm going to keep my non-unibody Penryn until late 2009 or early 2010, when we get Intel's newest chips, codenamed Arrandale. If you need a briefing about the chip, check here. To quote the article... I know many are staunch on their "if you need it, get it now" perspective, which I respect, but surely there are others like myself who will be holding out for this new Intel i7 based technology. If so, this is your waiting and speculation thread! Can't wait!!!
