4. Safari (iOS 6 and Mountain Lion)
iOS 6 will beef up web browsing across MacBooks and iOS devices. Apple will introduce an iCloud Tabs feature, which will keep track of pages you have opened and sync them across devices.
It will also be possible to save web pages to your Reading List, so you can view them offline. This feature will be restricted to the iPhone 4, 4S iPad 2, iPad 3 and beyond.
3. Ivy Bridge MacBook with Retina display
With the latest Windows 7 Ultrabooks all packing Intel's Ivy Bridge chipset, it's no surprise Apple has included the chipsets in the refreshed MacBook range. However, Apple has gone one step further and introduced a Retina display in the MacBook Pro lineup.
The 15.4in model will pack 5.1 million pixels, giving it a resolution of 2880 x 1800. This will provide unparalleled clarity of text and images on laptop-based devices.
Apple has also managed to reduce glare whilst increasing the contrast ratio by 29 per cent, compared to a standard MacBook Pro display.
There will also be the option of getting up to 512GB of Flash storage and battery life hasn't been compromised - with 7 hours being touted.
The latest MacBook Pros are available now, but they aren't cheap. A 15in MacBook Pro with a Retina display, 2.3GHz Intel Core i7 processor, 8GB of RAM, 256GB of Flash storage and NVIDIA GeForce GT 650M graphics card will start at 1,799.
