I'm on your side, I've come home twice to a cold house because the batteries died. Another fancy programmable one just quit working and again, house was cold. I bought one of those old fashioned round analog ones and I love it.
Before anyone mentions it: I am capable of remembering when to turn it up or down to save energy and I don't want one that will email me when it's time for new batteries
