The GE J1455 has a better sensor type than most similar spec digital cameras that are a comparable age to it. This GE camera has a CCD sensor type, whereas most similar spec cameras that have been available for around the same time as it have a MOS sensor type. CCD sensors produce high quality, low-noise images but consume a lot more power than CMOS sensors. CCD is the most common image sensor type used in digital cameras.
A CCD sensor type is actually the best sensor type across all comparable spec digital cameras that have been on the market for around the same time as the J1455.
A MOS sensor type is the worst sensor type across comparable types of digital camera.
There are a number of alternative digital cameras that have a CCD sensor currently available which you might want to look at including the Canon PowerShot G12 ($675.12) which has better reviews.
