Air texting: Joi has a great story on the latest gadget feature from the Nokia 3220: by waving your phone up in the air, you can produce letter-signs in the air. cool! now we all need to go and work out to muscle up that arm :D
This reminds me of another gadget seen at Cebit in Hannover earlier this year: phones that project an laser keyboard on a flat surface. A similar device is here: really interesting stuff.
