DoCoMo FeliCa mobile payments are so cool

From some Russel's tag search on YouTube of KDDI and DoCoMo, he found a commercial video from DoCoMo to show the Push To Talk and FeliCa system :

Talk ! Buy ! Talk !

I found the system so cool and simple to use.
Some days ago I read a post on Motorola that has announced an "M-Wallet" service "compatible with any cell phone or network".

I can't wait to see it in Italy.
