The iPotty is a training toilet onto which parents can attach an iPad. Apps are available to persuade their diaper-dependent offspring to wipe and flush. To be fair, more than a few people at CES lit up at the mention of this product -- but this probably has more to do with the fact that toilet training is so challenging as to make any beleaguered parent desperate for help. At least one doctor has already expressed doubt over its effectiveness, and one has to wonder, given the tantrums toddlers throw, whether you want your iPad anywhere near the process. It's terrifyingly easy to imagine a child who sees his first wipe not as a triumph but as an opportunity to apply a defiant smear across the device's screen.
