I'd be interested too, though I'd be surprised if they weren't all at it. Especially those who missed out on the smartphone thing.

Indeed :) Me too... I'm just assuming, given they have a captive audience, the hardware chops to deliver electronic devices at scale and a huge pile of cash, they would be foolish not to be working on it, while Google Glass was a headline failure, the Hololens most certainly is not, it's just received it's safety rating for on site use, the applications I've seen in use in industrial design show that this technology is not going away.

hang on... [edit]
