As I get ready yet again to head out of the International CES show in Las Vegas, I've been going through the mobile commerce potentials likely to be shown at the event. CES is an event where a lot of products that are technically feasible are shown in hopes that they may become commercially viable. Many do not. Before the official International CES opens on Tuesday, there are many private showings of some of the key innovations that will be seen by the public sometime later in the year.
