btw.. would changing to merom be considered a somewhat more of a upgrade than speedbump? i mean, would there be perhaps bugs coming out that's in addition to what's out there now? i'm a bit confused
Changing to Meroms will definitely be considered an upgrade(though it still uses the same logic board). There might be some new issues with it since it`s a new processor. But thats very unlikely. And in any case if you are not satisfied with it you can always use your apple care.
I`d definitely get the merom MBP (granted there is a design change too) without worrying bout Rev A problems. My rev A MB runs absolutely fine without any problems(`cept for a little heat may be)
