The Sony Ericsson K850i Cyber-shot features a second video calls camera, Bluetooth, USB connection, FM radio and a M2 memory card slot. A 512mb card is included in the box. Interestingly Sony Ericsson have decided to offer a dual card support slot on the K850i which can host not only the M2 standard but also Micro SD too. All these options add a little to the weight but the size remains the same as the K810.

The Sony Ericsson K850 offers a neat solution to navigation with the keys positioned around the number 2 and 5 keys to allow the larger screen to be used. The overall design is functional but certainly individual with colour accents down both sides.
