Today’s MBP debut sees the addition of a hyphen into quoted battery life spec, an addition which leaves Apple lying twice per machine – that or simply unsure of themselves. At least however, the MBP spec leak was wrong! The hyphen denotes a new automated graphics-switching technology which oscillates between GPU’s (Intel HD or nVidia 320 GT) for on-the-fly battery conservation. Apple claim 8-9 hours of use for their higher end 15 and 17-inch models and 10 hours for their single-GPU 13-inch model. Apple’s laptops never get their quoted battery spec, so it is reasonable to assume 6-9 hours of light use with the new machines, which while hardly marginal, should confuse spec-buyers.
For the geek, highlights include Intel’s new Core i5 and i7 processors (15 and 17 inch models only), the inclusion of fast GPU switching technology, and a fancy-pants nVidia 330 M/GT GPU* accomodates Intel’s slower Intel HD Graphics.
The new 13-inch MBP starts at USD 1199$ while the higher spec’d 15 and 17-inch models start at USD 1799$ and 2299$ respectively.
