Close. There never was a 13" MBP without FW. There was a 13" MB without FW, which got renamed to MBP when Firewire was added.2009. 13" MacBook Pro and the return of FireWire.![]()
There was a 12" Powerbook G4 (2003-2006) with FW. One could argue that it was 'replaced' by the 13" aluminium MB in 2008 without FW (but that is a two-year gap without any 'high-end' 12/13" Mac laptop). But by that token you could already call the 2006 white 13" MB as the 12" Powerbook successor. The white 13" MB got sold from 2006 through 2011. It was sort-of replaced as the entry-level Mac laptop by the 11" and 13" MBPs in 2010.
I don't think you can really quote the 2009 13" MBP as re-instating a feature that had previously be removed. It was rather a product line that was cancelled (12" Powerbook) that got reinstated with the 2009 13" MBP.
