"The car is the ultimate mobile device, isn't it?"
No. The JetPack2.0* is the ultimate mobile device and I'm still waiting for Google to pull mine out of their arse!
(* not 1.0, that will have garbage collection issues causing Android to stall and the customer/victim to fall out of the sky - ironically causing real garbage collectors to rush in to clear up, tripping over the open source contributors rushing the other way.)
GOOGLE, WHERE'S MY F'ING JETPACK!
