Quite frankly, the reason I won't be updating as of yet because I feel that the impending MacBook Pro update will just be a "bump." WWDC is the mainstage for the Pro equipment, and I feel that is when we will see new Apple Cinema Displays and a REAL "NEW" MacBook Pro.
The Penryn update is actually considered a "Santa Rosa Refresh." It still possesses the same mobile Intel 965 chipset and wireless wi-fi link. Montevina will have sure-fire HD support (HD/DVD & Blu-ray), will be 40% smaller than Penryn, brand new Cantiga chipset, and possible to have Wi-Max. Intel admitted that when Montevina is released, that is when we will see smaller and lighter laptops. Best of all, it's going to be released MID-2008, and what rolls around that time.... thats right. WWD
So let the true MacBook Pro update...wait.... REPLACEMENT.. wait begin!
