Heres some clues... The 12 inch PB was taken off the market with the iBook (rather than launching a replacement model). And lastly if you check out he macbook web page (http://www.apple.com/macbook/) you'll see that it say's that the family is now completed. Kind of lame I say. There really should be a high powered compact pro-series laptop. Thats a market apple shouldn't forget.
