The Acer variant costs $299 (USD) while the HP version is more expensive at $329. The two devices are basically identical in specification, though the HP version has a removable cable, which some analysts speculate is to facilitate the eventual addition of untethered MR experiences. The two headset are still listed as the Developer Version, though Microsoft’s Alex Kipman said at Microsoft’s Build 2017 event that the development versions will be fundamentally the same as the consumer versions when they are finally released. The Microsoft Store pages for the devices is offering free shipping and free returns for the devices, though as of writing the HP version is listed as ‘Out of Stock’. Other headsets are expected from ASUS, Dell and Lenovo.
