The Koreans have the up and coming release of the Sungju TangoX Nano Touchscreen UMPC to look forward to which, apart from sporting extremely compact proportions also comes with in-built Skype/VoIP capabilities courtesy of a removable integrated handset.
The TangoX Nano has a VIA C7-M ULV processor running at 1.2GHz, 1 gig of DDR2, your choice of a 40 or 80 gigabyte HDD, HD audio, a 7” 800×480 touch-screen. There is also a 4-in-1 memory card reader, Ethernet NIC, WiFi in A/B/G flavors, 2 USB 2.0 ports, DVI out, and the removable, yet built in, Skype/VoIP phone that you see next to the screen.
It is mere millimeters larger than the Eee and weighs an unnoticeable .05Kg more than the Eee. Measuring in at a mere 270 x 171 x 29.4 mm and weighing just 0.92kg. No word on price, but it doesn’t look like you’ll be able to get one outside of Korea anyways.
