Calling all cars, calling all cars... be on the look out for the SMS M500 GSM Watchfone. That's right, the first shipments of the M300 followup are said to be leaving Hong Kong as of tomorrow, May 30th. Now we can all get a little Dick Tracy with "the world's smallest mobile phone" -- or so says SMS Technology Australia. Unlike Dick's 2-way Wrist Radio which emerged in 1949, this pup goes quad-band GSM while packing a 1.5-inch touchscreen with itty bitty, built-in stylus; Bluetooth 2.0; and all the 120 x 160 pixel MP4 video (or MP3/AAC audio) you can pack into its 128MB of storage. The watch weights just 60-grams and should hold-up to about 200 minutes of talk or 80 hours standby before needing a USB recharge. Now if someone could just hook us up with a jetpack we can get to living in the future promised to us by Uncle Walt (no, the other one) in those free lovin' 70s.
