Just curious what makes/models and what you think of them - pros, cons, etc. They're really not that much more $$$ than a rider mower and personally I can't stand those (big, clunky, require a pickup truck to take them to service if they ever break, "lazy fat guy" stigma, etc.) I currently use a push mower but hate the time-suck aspect (I'm hardly ever at my house and when I am, I always have about 100 other more important things to do - I just don't want the place getting overgrown). These seem like a logical solution. Thoughts?

A few questions:

1. Are any models programmable insofar as their territories and "off limits" zones?
2. (Related) some models use a "perimeter wire". Is this as much of a PITA as it sounds to set up? Reliable?
3. Will they find their own chargers, plug in and then resume if needed? (I believe Roombas will do this)
4. Can they handle inclines well?
5. What happens if they get stuck? (Overheat? Damage?)
6. What kind of customer service do the manufacturers provide? (Stand behind the product or run-around / hide behind dealers?)

I'm researching Husqvarna, RoboMow and LawnBot. Pretty limited online reviews but maybe a few of you guys can give me a real testimonial.
