The P6000 is out of date, and has been replaced by the P7000. Here's what we had to say about the P6000 when it was released in September 2008.
The Nikon P6000 is a 13-megapixel digital camera that features built-in GPS functionality. The 13.5-megapixel compact point-and-shoot updates the successful P5000, adding in integrated GPS for those interested in geo-tagging. The P6000 offers automatic and manual controls, making it an excellent camera for both novices and experienced users.
