Holy moley!

iPod Photo — All your music and all your photos on an iPod.

A delight for the ears. A feast for the eyes. Though it’s no bigger than a pack of playing cards and weighs in at just over 6 ounces, iPod Photo delivers a one-two sensory punch. Letting you carry an entire library of your favorite music — up to 15,000 songs — or enough photos — as many as 25,000 — to fill nearly 200 slide trays or cover nearly 5,000 square feet of wall space.

Connect iPod Photo to a projector or TV and give slideshows — complete with music.

Update: iTunes 4.7 (now available) includes a very useful duplicate track feature.
