Surface Pro 3 promo touts $650 credit for MacBook Air trade-in

Microsoft is offering a limited time Surface Pro 3 promotion via which users can get up to $650 in store credit for trading in certain Apple MacBook Air models.

The new promotion, running June 20 to July 31, 2014 -- "or while supplies last" -- requires users to bring MacBook Airs into select Microsoft retail stores in the US, Puerto Rico and Canada. (The trade-in isn't valid online.)

Microsoft execs have been touting the Surface Pro 3 as the tablet that can replace users' existing laptops, including MacBook Airs. Microsoft's Surface.com site

The fine print:

"To be eligible for trade-in, device must power on to be considered working. Water-damaged devices and devices with cracked screens are not considered working devices for purposes of this offer."

All trade-ins are final and provided as part of the "Recycle for Rewards program" from CExchange. The trade-in is limited to one trade-in per purchase.

To get the maximum ($650) value, users have to apply the store credit toward the purchase of a Surface Pro 3, the most recent model of the company's Intel-based Surface tablets. The Core i5 version of the Surface Pro 3 began shipping on June 20.

There's no information on the Microsoft store site about which models of MacBook Airs are eligible for promotion.

Microsoft also, as of late, has been trimming prices on its second-generation Surface Pro tablets, clearing the way for the Surface Pro 3s.
