Nokia's SU-B1 Digital Pen measures 149mm by 23mm by 20mm and weighs just 35g, while this is a bit more than your average pen it packs a few more electronic tricks than a Bic biro, but it doesn't exactly look like a biro the LED's on the pen give it away at being something out of the ordinary.

The Pen can sit on a USB dock which allows it to connect to your PC this also allows it to charger with a Nokia phone charger plugged into the base of the dock, you can also directly plug the charger to the pen if you are away without the dock. The pen uses special digital notepads that can sense what the pen writes. The pen stores each page of each pad as a file so you can recall files later on your PC. The notepads contain normal paper with a specially printed digital pattern. Pages have boxes containing pen commands. Just tick the send box and your page will be sent to your compatible phone or PC. The possibilities are great but we worry just how often you will be carrying "digital paper".

Yes the SU-1B can store up to 100 pages of A5 data but do you have that much digital paper? its one thing to take the pen out with you to a meeting or lunch but do you want to take your "special" pad, if you do then the files are saved as PGD's pen generated documents, it is possible to save as other formats when working in digital note viewer on your PC the Pen's software syncs with MS outlook PowerPoint and word.

The Pen can also work with MMS phones via Bluetooth, you can draw a sketch or map and send it to a Bluetooth enabled phone within 10 meters and then onwards as an MMS, Nokia claim it is compatible with their latest crop of Bluetooth phones but we also found it to work with the top end Sony ericsson phones.

We love the idea of the Nokia SU-B1 but perhaps the world isn't ready just yet, the docking procedure was a bit of a pig, with us having to switch of antivirus and remove other Bluetooth devices including our TDK wireless card before we could connect. Plus the need to carry digital paper to make this anything more than a flashy biro really limits its use.

Perhaps the next generation of pen will not need the paper and allow us to capture days worth of scribblings and diagrams now that would be useful.
