If you're considering laying down some of your hard earned money for a brand-new model one of Apple's bestselling personal computers, you may want to consider which one is right for you.

MacBook Air and MacBook Retina each have tons of slick new features, and some rumors have indicated that these latest versions may even include a touch-screen!

The new MacBook Air is the slimmest and lightest yet, meaning that it is highly portable and easy to slip into backpacks, suitcases, or luggage. If you are looking for a laptop that has the maximum portability and you are constantly on-the-go, then this is the major advantage of the Air.

Due to heightened processing capabilities and certain new specs this version of MacBook Air is the most accommodating ever: "Everything you do is snappier and more responsive. MacBook Air even wakes up faster than ever, thanks to flash storage and the latest Intel Core processors," says the Apple Website.

Compared to the Air, the Mac Book Pro is bigger and sturdier - although certainly less bulky than previous models - and can be purchased in a 15-inch or 13-inch screen version.

The Macbook Pro Retina has a greater memory capacity, and obviously does have more power underneath the hood than the Air. Pro Retina includes an amazing screen display that will provide a premium viewing experience for those using media on the computer.

Both Pro Retina and Air, although more likely Pro, could be equipped with a touch screen, according to a recent patent submitted by Apple. This would give the company a greater boost in their competition with rival products such as the ChromeBook.

In addition, some comment this could be the first step for Apple towards a lap-top that has eliminated buttons altogether.
