Trying to understand what the core O/S is now, and how will it (the O/S) be updated and patched on the 6600m in the future.
Couple things on the "M-panel":
FRS wasn't saying who the partner was for the controller nor the new screen.
One FRS team member said Gerald led the design of the NEW interface for the "M-panel" which to me suggested it is a bespoke design, rather than an imbedded product.
I did not get a clear answer if the new device was running with shared resources from the radio, or an additional processor like the Maestro. I don't think I asked the question in a way that made sense to them.
On the Maestro, please remember the embedded hardware is running a CLOSED commercial version of Windows and the FRS controls any updates/patches. You can find other threads discussing this difference.
I don't see that as a positive thing. As someone who works in InfoSec, I would regard that as an even bigger risk. Anything or any company that could slow up to automatic and immediate dissemination of updates on Windows devices is bad news. i.e. when the next WannaCry like infestation happens, and the FRS team are enjoying their sunday BBQ, how quickly will every Flex device world-wide get a) detected and b) patched?
Windows runs in tens of millions of embedded systems every day. Among the ones I've personally worked on are: Medical imaging equipment, blood analyzers, military UAVs, financial clearing imaging systems, factory floor automation in all manner of industries, mass mailing systems, and almost every ATM on the planet.
So, relax. If Windows was really such a mess, the entire world would be in chaos. Your CT scan would be dangerous. Drones would fall from the sky. You'd never be able to get cash without waiting in line for a teller.
Your radio or your Maestro is in good hands.
