Agreed: One sunspot or gamma ray burst and your Nexus One will stop working very rapidly. The "age" of rad hardened devices is pretty much limited by the processes used. Only simpler designs work well. The finer the traces, the more charge-related problems occur and the less reliable they will be. Also, there's not much interest in making it better because it works fine as it is. If you take away the JVM, most of the OS, the graphics stack, comms layer and all the fancy abstractions from the Nexus One and Android OS, a 1MHz RCA 1802 is fine ;-) Simple is good enough though when you read a bit of telemetry and you use low bandwidth RF comms. Also the Nexus is a really bad idea as it contains FLASH, which if you fart any radiation near, it flips bits like crazy.
