The difference between being woken from a dream and woken from light sleep is the difference between a rotten wake up and an easy one — for me at least. I have long dreamt (heh) of an alarm clock that is smart enough to tell the difference, and now I've found one:
The clock, called SleepSmart, measures your sleep cycle, and waits for you to be in your lightest phase of sleep before rousing you. Its makers say that should ensure you wake up feeling refreshed every morning.

Update: d3 sez, "They mention a prototype might be ready by the end of the year, but there already is an alarm clock that performs a similar function available now called the SleepTracker."
Update 2: Richard sez, "my Gadget Show Podcast still has a competition open to give away a Sleeptracker. Listen to the show and send in the requested suggestion, and I'll be happy to send the winner, as determined by Eric Mack, the watch that was provided for my review (only worn for a week)."
