Alas, I find the new feature to be more promise than practical, based on the brief time I had with the phone at this week's Mobile World Congress wireless show in Barcelona, Spain.
But first, I'll go through other features that may appeal to some people.
The phone is due to come out in March. Sony hasn't announced a price, though its phones typically sell for $500 to $600 in the US without subsidies or a contract.
