I'm a huge fan of robots. Life should be simple, but robots can still fulfill a need to automate some of the more mundane tasks in life. I have 2 Roombas and just ordered the new 560 (quieter and more reliable) and a Dirt Dog robot for the garage. I love these things. I love the satisfaction of pulling out the bin and finding all the cat hair and dust they collect. Yeah, I'm a nerdy gadget freak, ok.
When we travel, we setup a wireless G camera that senses motion and emails me with photos. This way, we can make sure the cats are still moving around the house, and no bad guys are doing bad stuff.
iRobot is getting set to release this little gem. Wow, can't wait to get my hands on one. What a great way to keep tabs on your house when you're away.
