Microsoft took a shot at Apple in its blog post on Monday, calling its rival’s new MacBook Pro a “disappointment.” The Redmond, Washington-based tech giant is also claiming that an abundance of Mac users have already switched to its hybrid Surface devices.

Microsoft was evidently ecstatic in its blog post, not only touting the success of its Surface products but also opening fire at Apple. The Windows maker said that more users are ditching Macs and moving on to Surface now compared to previous instances.

“More people are switching from Macs to Surface than ever before. Our trade-in program for MacBooks was our best ever, and the combination of excitement for the innovation of Surface coupled with the disappointment of the new MacBook Pro – especially among professionals – is leading more and more people to make the switch to Surface,” announced corporate vice president of marketing for Microsoft devices Brian Hall in the blog post. “It seems like a new review recommending Surface over MacBook comes out daily. This makes our team so proud, because it means we’re doing good work.”

Microsoft did not disclose any data about its claims. The company only stated that its Surface line-up, which includes the Surface Pro, Surface Book, Surface Studio and Surface Hub, is having its “best holiday ever.” Microsoft says it scored big on Surface devices last November, selling out exclusive Best Buy bundles in just one day.

Back in October, Microsoft offered to pay Mac owners to trade in their Apple laptops and use Surface computers instead. The company agreed to pay up to US$650 (AU$850) to any Apple laptop owner in the US who were willing to switch from a MacBook Air or MacBook Pro to a Surface Book or a Surface Pro. The strategy somehow pulled off and contributed to the Surface’s success.
