Hi there! I know that in the past, Apple has had refreshes of MBPs in October and in April....have any of you heard anything about an upcoming October refresh on MBPs? Thanks! 
well the buying guide will give you a good idea, but i expect the april-may next year, there is supposed to be some significant new processors coming out so theres no point in apple rushing the refresh
Yes buy now...I'm ordering mine tomorw with the iPod touch and printer...
What about an update for 13"?
Sure 15" were updated, but 13" is still C2D. Don't think there needs to be an event for that. Just wake up one Tuesday and its i5 13" MBP. Hopefully a better screen too.
Apple would have done that in April if that was what they wanted. Steve clearly said Apple chose better graphics and battery life instead of the new CPUs. Any update before Sandy Bridge is useless
Huh? 13" MBP is not an ultraportable. Shd have the same specs as 15"; 330M and i5. Seriously, how can you defend C2D? And don't use Sandy Bridge as an excuse to everything.
You can go C2D -> i5 -> Sandy Bridge or whatever; there is no reason so skip i5 entirely. Doesn't i5 have better battery life than C2D anyway?
Apple uses 25W C2Ds in 13" and 35W i5/7 in 15" and 17". There are 640LM and 620LM that are 25W but they cost as much as the 620M which is used in high-end so there is no point with that unless you want to pay 2000$ for 13". If Apple used the 35W variant, then you would be stuck with Intel IGP. Also, it would be ridiculous if 13" used the same CPUs as 15" and 17" as then people would not fork out the extra $ for more expensive models which is exactly what Apple wants you to do, to pay more. i3 wouldn't even be an upgrade due lack of Turbo.
C2D was a compromise. Seriously, it was the best solution. You don't want i3 and Intel IGP, they suck. i5 and discrete GPU is way too expensive and then you would get nasty battery life. Honestly, people are too fussed about these iX CPUs. Yes, they are better but not that much. For an average Joe, it doesn't make any difference
This does make me wonder what's going to happen with Sandy Bridge, seeing as everything is on the die. Would there be any way to use a dedicated graphics card?
