Does anyone out there have any experience with portable music playback devices? I was wondering if the i-Pod is any good, or are there portable rbcd players that do not skip and eat batteries?...I have read the discussions that are posted, and it seems that there is a lot of animosity in this group (rbcd is better than sacd and is better than vinyl and is better than live????? I just enjoy listening to good music irregardless of the FORMAT)...I am not looking to provoke...just wanting something that I can take while out on a walk or a run or a bike ride... any sugestions?
