Axxen's Skype USB pen has a standard USB connector at one end and a mini jack at the other for plugging in a headset. When plugged into a PC, the pre-installed Skype client fires up.
The WowPen Memo from Wow Technology is a device for recording notes you make on pads of paper. It clips to the top of a pad and records movements from the special pen that is included in the package. A mini USB port means you can then plug it into your PC where the software will download your scribblings either to be stored in a graphical format, or run through the OCR software so it can be turned into text.
Wow Technology founder Anders Bergstrom said he expects it to be available for about Â£130. A wired version, the WowPad Digi, will cost a little less.
