Sony Ericsson may not be as large as Nokia and Motorola, but its fans are one of the greatest ones. After all, not many brand-lovers produce that many concept designs. Latest in the series is touted as the KXXX concept, and features a widescreen display, touch sensitive keys, WiFi and a GPS. C’mon Sony Ericsson, this one looks really promising – find the designer, hire him and turn this baby into a real handset.
