US Army may be about to 'waste' up to $22b on Microsoft HoloLens
The US Army could end up wasting much as $22 billion in taxpayer cash if soldiers aren't actually interested in using, or able to use as intended, the Microsoft HoloLens headsets it said it would purchase, a government watchdog has warned.
In other words, the Army hasn't yet fully determined if or how service members will find these HoloLens headsets valuable in the field. Although the heavily redacted report did not reveal soldiers' responses to the prototype testing, it said feedback from surveys showed "both positive and negative user acceptance."
