Do you listen on your Android, iPhone, BlackBerry, or Palm phone? Replacing a stand-alone MP3 player with the cell phone in your pocket makes life a bit easier. But the default music player often doesn’t meet the requirements of serious audiobook addicts. I received an email from blog reader Judd who’s developed his own player available on iTunes – you can check it out here. I’m sure there are other iPhone audiobook apps readers have tried. As an Android phone owner, I’m looking for a good audiobook player for titles ripped from CD. And what about BlackBerry & Palm users? If you’ve made the shift from MP3 player to cell phone as your audiobook player, share your expertise! Add your recommendation for best audiobook app to the comments – you’ll help plenty of other audiobookers make the switch. I’m ready to ditch my trusty old iPod and lighten the load in my pocket!
