Gizmodo had an interesting entry about KDDI's AI-MATE (see photo to the left), a prototype which the Japanese operator is calling a "hybrid communicator", blending the functionality from a cell phone and a PDA.  The model will make its debut at the Expo 2005 in Aichi, Japan (which begins on March 25th).

On a separate note, we can add a couple more datapoints to the "Chaku-Uta Full" polyphonic tones download service that I wrote about recently.  KDDI announced earlier this month that the service surpassed the 3 million download mark on March 1st, after surpassing 2 million downloads earlier in February (on Feb. 5th).
