The honeywell touchscreen models are also fully programmable and I
believe will solve problem number 2. Not sure if any solve #1 though.

But, I don't think #1 is that big of deal. If the heat comes on 10
mins before the setback, all that means is the house will have a little
extra heat, so the heat won't need to come back on for a little longer
during the setback. In essence, it means the setback period could
have been 10 mins longer, but that diff is so small it's not going to
amount to anything really.

And, in fact, having a thermostat that's smart enough not to come
on within 10 minutes of the set-back period is *EXACTLY* equivilent
to setting the set-back period 10 minutes earlier.

No it's not, since you don't know when the last cycle will begin. In other
words, if you set the set-back time 10 minutes earlier, that wouldn't
prevent the thermostat from calling for heat one minute before that. What
I'm looking for is either the thermostat not calling for a new heat cycle if
it's within x minutes of the setback time, or keeping the equipment on for a
minimum cycle time, even if that means continuing to operate for a little
while after setback time.
