I don't know many people who listen to their MD's for more than 27 hours at a time. :happy:
And considering that we're moving around 1Gb of data instead of 150mb for the same comparative AA battery, your stats actually show good battery times.
But regardless, I'm truly sorry for the people who expected Hi-MD to last 80 hours a day. I bet Sony will be losing a lot of customers from that demographic.
