Today, had a new Mini experience that has not happened to me before.
Turned on display. Blue screen, with the "wait a moment" little circle thing rather than the normal behavior where it asks if you want live TV, etc.
Waited 20 minutes, just to give it time. Never changed. No response via remote. Only recourse was to unplug mini. After about a 7 minute boot cycle, it came up normally.
No power issues (it's behind a UPS), no Fios issues, nothing happened to the host, etc. It just barfed for no apparent reason.
Just sharing in case anyone else has experienced this new feature.
