After offering $200 for an iPhone or iPad, Microsoft is back with another promotion designed to tempt Apple hardware owners over to its own devices. This time it’s the Surface Pro 3, "the tablet that can replace your laptop" according to Microsoft. The software giant is offering up to $650 when MacBook Air owners trade in their laptops for a Surface Pro 3 between June 20th and July 31st.

A Microsoft spokesperson told The Verge that all models are eligible for the promotion, but the amount it will pay out varies on the specific model and its condition. The MacBook Air laptops must also be in working order and traded in to one of Microsoft's Stores in the US and Canada.

It’s no surprise that Microsoft is targeting the MacBook Air with its latest promotion. Surface chief Panos Panay spent a large amount of time during the Surface Pro 3 press event comparing it to the MacBook Air in terms of weight and thinness. Microsoft truly believes its latest model can replace a laptop, and it’s positioned directly to compete with Apple’s MacBook Air. Microsoft’s latest offer follows a similar offer from earlier this year when the company targeted PS3 owners with $100 to trade-in for an Xbox One.
