Kept the original specs , decided that i would use the 3.7 volt most of all. 6 volts for fun once in a blue moon, but i really wanted the battery life over and above anything else. Plus i can get a 5volt Prodigy anytime, yet i believe Cash will not offer the original specs again. I stand to be corrected though. Its like with my PS3's, my launch 60gb has 4 usb's,plays all ps2 games and plays SACD's, my brand new 80gb has 2usb's,plays no ps2 games and does not play SACD's. I would always choose my 60gb even at a premiun price because its more versatile. I love having the newest gadgets on the block. Remember the old guy saying...Those who die with the most toys WINS
