I'm not suprised that the iphone crashed, it's rubbish, the computer that i'm typing this on has been running for over 4 years with no crashes and only having to reboot for updates, so the argument against computers assisting would have been valid in the days of windows 95-vista, but a modern pc running a linux derived OS with good software can run for years and with the size of systems now it's possible to have 2 systems running in space smaller than a hard back book so there is no reason for not having a back up in case of hardware failure.
Wellwellwell, at least Honeywell have not figured out to make an avionic suite that does everything they advertised it would on a 2007 Sovereign.
The real issue here seems to be software.
But I´m sure Fatmanmedia LLC. could develop that way better than that small local radio shop Honeywell.
