Apple used the WWDC keynote to announce more details of Mountain Lion - the next version of its Mac operating system, which is released next month - and iOS 6, the latest update to the operating system that powers the iPhone, iPad and iPod touch.

But the most groundbreaking announcement was the new MacBook Pro with a 'Retina' display, The Telegraph reported,

What WWDC demonstrated was how, after several years of rapid expansion into new product areas, Apple’s products are now starting to come together again. Mountain Lion and iOS 6 share plenty of features, particularly the iCloud integration that allows content to flow freely from, say, smartphone to laptop.

Meanwhile, Apple’s MacBooks are starting to show the influence of iOS devices in numerous ways, whether it’s gesture controls on trackpads, high resolution displays or the fact that the computers are more likely to be sealed units, not upgradeable by users once they leave the shop.
 

Apple is not the first to do these things but it is doing them with an elegance and simplicity that many of its competitors struggle to imitate.
 

The screen on Apple's new flagship laptop, the MacBook Pro with Retina display, has to be seen to be believed. At 2880 x 1800 pixels, it can deliver double the screen resolution of the previous MacBook Pro and the difference is like putting on a pair of glasses for the first time.
