It's been mooted for some time, and prototypes have been floating around for the last 18 months, but Polaroid has finally announced the launch of the Polaroid PoGo Instant Digital Camera, the first portable digital camera and instant printer combination. With the push of a button, users can select from among the digital photos on the camera, crop or edit them and in less than 60 seconds, print full-colour, 2x3-inch prints -- all with a single device.

The Polaroid PoGo Instant Digital Camera is the second product in the Polaroid PoGo family of products. Like the Polaroid PoGo Instant Mobile Printer, whichwas released in July 2008, the Polaroid PoGo Instant Digital Camera uses the same ZINK Paper and ZINK Zero Ink Printing Technology from Polaroid-offshoot ZINK Imaging. ZINK is an ink-free printing technology which replaces ink cartridges or ribbons with ZINK Paper -- a composite material that has embedded, heat-activated dye crystals. Before printing, ZINK Paper appears white like regular photo paper. Once the pictures are printed, they are immediately dry to the touch, durable and smudge and water resistant.

The Polaroid PoGo Instant Digital Camera offers a full-feature digital camera with 100 percent inkless printing, 2x3-inch sticky-backed photos with or without fun borders and the advantage of reviewing the captured photos on a three-inch colour LCD screen before printing. The instant digital camera measures 4.7-inches wide by 3-inches tall and weighs only 10 ounces.

The Polaroid PoGo™ Instant Digital Camera will be available in the US from March 2009 for $199 (around £135). Ten-packs of ZINK Photo Paper™, which can be used in both the Instant Digital Camera and the Instant Mobile Printer, retail for $4.99 (£3.40) and 30-packs for $12.99 (£8.80). UK pricing and availability hasn't been announced.
