The latency claim is totally unfounded, and anyone who has made use of an embedded platform (even as weak as PIC or Arduino) to collect data can see it as totally and utterly wrong. Where is the latency coming from, then? Other than disputing what I wrote, no explanation of where the latency is coming from has so far been offered. I will gladly accept an explanation where the latency is coming from, and have even listed concrete models, years, and scenarios to facilitate a concrete explanation. Please, have at it.
