Coolest gadgets to kick off summer

Some people use long summer weekends to get chores done around the house, like mowing the lawn. This is an acceptable life choice, but if you happen to have a spare two grand, there might be a better way. The Automower from Husqvarna is like a Roomba for your lawn. The robotic lawn mower can move around obstructions and up hills, and you can set up borders to keep it from wandering off. Naturally, you can control it from a smartphone app -- preferably from a pool.
