They're using QNX. Google it if you don't know what it is. QNX runs the parts of the world that Linux can't (that is, QNX is a real-time OS while Linux isn't). The OS is very well known and liked despite being a proprietary Unix unlike Linux or even Apple's Darwin kernel (AKA Mach kernel to those who use some type of BSD). The OS is complete and conforms to the Unix standard (unlike Android).
While I'm not a fan of it being closed-source, I would never say that the problem here is the OS and it's real-time design makes it much more responsive than any other smartphone OS on the market today.
All that said, I'm still not sure about the UI design. I imagine that it will be a pain for beginner users and well-loved after the gestures have been adapted to.
edit: A word about OSX security. Dancing pigs
security is a problem with any consumer-facing OS. Vista tried confirm/deny security prompts and quickly proved that real security doesn't matter to the majority of end users (while the prompts were discovered to be easily bypassed, the point still stands that the security ideal was sacrificed on the alter of ease of use). OSX permissions (and any *NIX permissions, esp Linux with AppArmor or SeLinux) are much better than Windows. The difference between OSX and most Linux distros is that OSX attempts to avoid the dancing pigs problem weakening security for a better user experience. This doesn't make it inherently less secure than any windows computer running Admin by default and allowing execution privileges to any program that asks.Edited by hajile - 12/12/12 at 8:51am
