Even more than a robot that mows my lawn, I lust after one that would shovel my walks. The older I get, the colder it feels as I haul out my snow shovel each winter and clear away the snow. The i-shovel waits for the flakes to fall and then starts shoveling the driveway while you sip hot chocolate huddled by the fireplace.
Since this beast isn't available for sale yet, I may just move further south to a townhouse and get a Roomba to sweep my house while I sit in my Bermuda shorts sipping something cold on the rocks.
