Trouble sleeping? Join the club. Zeo aims to fix that with its Personal Sleep Coach, a clock with a remote headband that reads your brainwaves. Data about your brain activity during sleep zaps back to the clock, recorded on an SD card that plugs into your PC, uploading its results to your online Zeo account. Could this be even more sleep-aiding techno-hooey?

The idea is, you can see exactly how well you sleep each night, and you'll know which of Zeo's sleep suggestions work the best. Does it work? Well, that brainwave-reading headband sounds fascinating if a bit far-fetched, and it'll cost you $400 to find out if it works for you. If it's a failure, I could recommend a podcast or two that might induce sleep a lot more efficiently. Meanwhile, here's a pic of the magic headband at work:
