“What is the battery life of this sansa version? BL(battery life) is always a huuuuuuuge decision for ANYTHING I buy. I was wondering what the BL is on this particular Sansa. I know that the BL on (SanDisk - Sansa Clip+ 4GB* MP3 Player - Black/blue/red/purprle/ect.) is approx. 5 hours (I also know that the BL in years is amazing compared to pretty much if not all Ipod's and other mp3 players) but I was wondering if the BL on this particular Sansa when fully charged is longer or less. If I can get comparisons to the BL on other Sansa without having to buy them all, that would be nice too, thanks.”
