Actually as I understand it, where heat is involved in chip
failure, leaving the chip on all the time is not much more
damaging than never turning it on. The stress comes from
materials expanding and contracting with heating and cooling
cycles, so if it's on 24/7 it only needs to survive
heating/cooling during the odd blackout. On the other hand, if
it were turned on every morning and off every night, the
stresses could quickly cause failure. That's what I read
somewhere anyhow...
By the way, how does the Plus4 Caller ID system work?
