The MacBook Pro is the Intel-based successor to the PowerBook range.
After a series of minor design updates, it was completely redesigned on 2008–10-14 and had an SD slot added to most models on 2009–06-08, at the expense of the ExpressCard slot. On that date, the range was also extended “down” to the 13” model, making the Pro moniker synonymous with the unibody aluminum housing again.
