Sony Ericsson Chatpen CHA-30

Although Sony Ericsson’s Chatpen CHA-30 is rounder than the similarly Anoto-based <A href="http://reviews.zdnet.co.uk/hardware/inputdevices/0,39023910,39119056,00.htm">Nokia SU-1B Digital Pen</A> and less comfortable to hold than the equally rotund <A href="http://reviews.zdnet.co.uk/hardware/inputdevices/0,39023910,39118051,00.htm">Logitech io Personal Digital Pen</A>, it makes up for these drawbacks with its impressive connectivity. A notable difference between the Chatpen and Logitech's and Nokia's devices is that the Chatpen has no USB connection. The charger fits in the end opposite the nib and all data transfers are wireless, via Bluetooth.
