I'm thinking the post above missed the point. Yes, a wide variety of modern gear does not fully turn off - small portions of its circuitry remains running to allow things like the remote control to work.
I'd rephrase the question to: "Does equipment last longer if run much of the time in standby?"
An argument "for" might be that with a high percentage of the component powered down, at least that large part of the equipment is not wearing out faster due to being in a full powered up state.
An argument "against" might be that since part of the equipment is on regardless, that part suffers the extra wear of being powered up and becomes the weakest link which can still break and cause the whole component to be effectively failed.
Tie breakers/makers include the fact that the life of a lot of modern electronic components is not that strongly affected by being powered on or off.
The estimate of 99% of the component being powered off when the component is in standby is just that - an estimate and the simpler stuff like a BD player may drop below that percentage.
I turn my AVR and BD player off when I'm not using them, but for my convenience I leave a few other components on 100% of the time. OTOH my computers never get turned off for my convenience.
