I have no skin in the game and no intention of buying anything for another couple of years at least, FWIW.
Anyway: Sibling post says ~5 seconds from standby - Which seems very reasonable to me, so I suppose it's just lack of compelling features (subjectively to the people in question, not regular users) that result in the 'gathering dust'... Which means the people I have spoken to haven't wanted to bother keeping it on standby (thus increasing the barriers further).
