Back in the beginning of March, Microsoft said that development units of Acer's mixed reality head-mounted displays (HMDs) would begin shipping that month. That never really happened though, but today, at the day two keynote for the firm's Build 2017 developer conference, it confirmed that pre-orders would start today.
In fact, despite all of the attention on Acer's HMD dev kit, HP is also offering one that's up for pre-order today from the Microsoft Store.
The devices will be made available in the US and Canada, and if you order now, they'll ship "later this summer." The model from Acer will cost $299, and HP's HMD will cost $329. They won't include the motion controllers, which were unveiled today, but when these devices are generally available, the Acer HMD will have a package that includes the controllers for $399.
Of course, Acer and HP aren't the only companies that are working on Windows Mixed Reality HMDs. Later on this year, we should also see headsets from Dell, Lenovo, and 3Glasses.
