Another 4G UMPC

Raon Digital has announced a new WiBro device for Korea and it makes me wonder if devices like this will be successful in the U.S. when Sprint has completed their XOHM roll out? UMPC devices really facinate me, because I'm not sure the right design has been demonstrated yet and the other question I have is who do you market it to? Is it the business traveler, the student? It will be interesting to see if these ever gain any market share from laptops. More details from aving.net below.
"SEOUL, Korea (AVING) -- Raon Digital announced the release of its new UMPC ‘EVERUN’ equipped with built-in WiBro module in Korea market, which supports 802.11b/g WLAN, Bluetooth 2.0 connectivity and HSDPA/Wibro.
