Perhaps taking a cue from iPhoto's whiz-bang smart organisation features, PS3 firmware 2.60's biggest add is a new Photo Gallery app that looks like it can sort photos in some interesting ways.
The app can detect faces (though it doesn't sound like it can spot individuals like iPhoto '09 claims), and can organise by whether people are smiling or not, how old the subjects are, colours, landscapes, and that kind of thing. Looks like a typically Sony interface that might be fun, if you make a habit of storing photos on your PS3.
Other updates include support for the new 3.11 version of DivX encoding and guest access to the PlayStation store. Whoopeee. [PS3 Blog]
