An interesting post over at AppleInsider suggests that because of today's speed bumps to the MacBook Pro line, this may mean that the hopefully soon to come Intel iBooks (or as I think they'll be called, the MacBooks), could include the slower 1.67GHz Core Duos rather than the earlier suspected 1.67GHz Core Solos. Their argument that it would only cost an additional 32$ to include a 1.67GHz Core Duo than it would cost to include a 1.67GHz Core Duo, seem to make a lot of sense.
