I don't understand why these products are always pitched as a consumer product when this is an enterprise dream come true. People are fickle and refuse to change their personal habits, but using my phone as a thin client sounds a lot more appealing than having separate laptops for work & play.
The problem I see with this is that, even if the phone is work property, it's still often used for play as well as work (because who carries around a work mobile as well as a personal). Blackberry tried to address this problem, but I think we all can agree that they were unable to address pretty much any problem at that point. A little OT but... I'd very much like to see a Qubes-like OS for my phone, so I can use one…
A lot of people carry around two phones, specifically the same type of people who have two laptops.
