Microsoft yet again lowers US Surface Pro 4 and Surface Book prices by $150

In a world where convertibles appear to be gradually eclipsing the popularity of both traditional laptops and tablets, Microsoft isn’t afraid to constantly reduce its Surface Pro 4 and Surface Book profit margins if that means gaining the upper hand over Apple in terms of market share.

Of course, it’s not like these 2-in-1 Windows 10 beasts are sold at a loss for $850 and up and $1,350 and up respectively, so the Memorial Day sale currently ongoing on Redmond’s US e-store is a win-win situation.

For a limited time only, i.e. until Monday, May 30, select configurations of the two hybrid machines net you a cool 150 bucks in savings each… once again.
