Query: Couldn't make it work with my Mac

Despite being a mac user, I really wanted to get away from ipod and this seemed to be pretty much the only other mp3 player that was compatible with macs. Since it also had great reviews both here and on cnet, I felt pretty comfortable ordering this product. Well, it may indeed be compatible with macs, but for the life of me, I could not get it to work. I'd converted all my itunes stuff into mp3 format, but could not get any music transferred onto the player. I'd read in some of the reviews that Cowon's instructions tend to be fairly cryptic, but since I'm pretty tech-savvy, I was not dissuaded. Now I wish I'd been more wary! I finally gave up and returned it to amazon and ordered, of course, another stupid ipod.
