Quick Review- Epson P-2000
You will probably find the 40GB to be useful. The actual usable memory is about 36GB. The size of digital images is increasing yearly, so your next camera(s) may need additional storage. In addition, if you shot RAW (about 8.7 MB per image with a Canon 20D), or you are on a trip for serveral weeks where you do not have accesss to download you will need the additional memory. I do, however, know how you feel. My first Epson was the P-1000 with 10GB and I was using a 3MP Nikon and I could not imagine how I was going to fill it up. I did.
