It does not seem to be that great.

"The bottom line: Great performance and solid design can't get past the HP Photosmart R847's major image deficiencies." 6.2 out of 10
HP are not very serious about their camera division and are not known to put out award winners. It is typically better to go with someone more in the camera biz like Canon, Nikon, Pentax, Fuji, Olympus, etc. Kodak is the one exception IMO though. They are decent and easy to use, but are certainly not innovators.
