Now that Apple has added Intel Haswell processors to both its MacBook Pro and Air lines, many customers may not be sure of which computer to go with. Both provide excellent performance, mobility and battery life. So what are the main differences and how should users decide?

If your priority is mobility, then it's hard to beat the MacBook Air. The 13-inch model can run for up to 12 hours on a single battery charge, making it ideal for users who plan to be away from power outlets for an extended period of time such as when they're flying, commuting or carrying their device around the office all day for meetings. Both the 11-inch and 13-inch models weigh less than three pounds.

But if you want your laptop to come with sheer computing power, even if it's a little bit bigger, you should definitely give the MacBook Pro a look. The CPU options available for both the 13-inch and 15-inch Pros offer twice the speed of the MacBook Air, and you can expand the flash storage drive of the 15-inch version up to 1 terabyte, while the Air tops out at 512 gigabytes. The Pro also comes with Intel Iris graphics processing capabilities, meaning that it can better handle tasks involving 3D rendering, video production and high-end photo processing, all of which will look stunning on the Pro's high resolution Retina display. However, keep in mind that the battery lasts up to 9 hours on a charge, still spectacular but not quite as long as the MacBook Air.
