Very excited to hear that the LG watch phone is finally going to arrive in the Uk very soon. The details are here http://www.techdigest.tv/2009/07/lg_gd910_watchp.html
I have played with a few watchphones over the years – I remember a Motorola one from back in 2001- and they are a huge amount of fun. The last one I looked at was thjs http://www.iwantoneofthose.com/swap-watch/index.html which worked really well and was surprisingly easy to use. My only real issue is with watch phones as a format. You can’t obviously take speaker phone calls on the bus and that means having to wear a headset.
Still if you are the sort of person who is permanently connected to a Bluetooth headset they really are a no brainer. I think we will see quite a few of them, in the coming months
