This week at CEATEC, Fujitsu demonstrated two portable tablets running on Windows 7. The pair are prototypes for the moment, so sadly no specs were revealed. The company also showed off a Design Concept flip phone, which sported dual touchscreens that can rotate to offer a landscape view.

The handset was preloaded with Fujitsu’s proprietary OS, which could hold it back big time if or when it’s launched since the apps market isn’t likely to be capable of competing with the Android Market or iTunes store.

Sharp has been busy showing off the NetWalker at this year’s Ceatec.The NetWalker is a smaller-than-usual notebook sporting a 5 inch touchscreen, Ubuntu OS, USB, Wi-fi, 4 GB memory, microSD expansion and a battery that will last you up to 10 hours.

The Sharp NetWalker is set to be priced at about 44,800 Yen (or $500) and is expected in Japan by the end of October. We can only hope that it shows up elsewhere too, for those who love small.

JVC enters the HD pocket camcorder arena with something new at CEATEC today, with the Everio HD Memory Camera. This SDHC based concept camcorder is expected to be AVCHD ready with an HDMI port. You’ll notice that most of the buttons are conveniently situated within finger distance at the top of the device. There isn’t much info otherwise, but more details will be forthcoming.

Remember Murata’s amazing bicycle riding bot? Well, they’ve created a girl that basically one-ups the poor guy and shows him up by riding only on one wheel. Her name is Seiko, a 20-inch tall, 11 pound unicycle riding robot. Just like her male counter-part, Keisaku-kun, Seiko sports a chest-mounted gyro to keep her upright and uses Bluetooth to communicate with a PC that gives her instructions.

If you find yourself in Japan, you can watch the whole family of robo-daredevils do their thing at CEATEC Japan 2008. One-upped by a girl who only needs one wheel? That sucks. Check out a video below of the original, our favorite bike riding bot, casually riding around looking like some robo-hoodlum up to no good.
