Looks like good tech, but I'm kinda torn about whether I'd like to use it, or not.

Yes, it'd be great to 'set it and fotget it' - one less job to worry about. But, there's something satisfying about mowing the lawn, and it's one of those tasks which helps me think.

When you're doing something "mindless" and repetative, your sub-conscious has time to step-in and work on the things your conscious mind has been busy on. There's also the "white noise" of the mower engine too. It's similar to why you get so many A HA! moments in the shower.
