Don't have one so I don't know how good it is (I've heard and read complaints over its UI, but it's supposed to be one sweet sounding device). Was one of the devices I did cursory research on before I bought my Sony X1061, and I remember reading that it has Bluetooth 2.0. Also I recall that it handles Audible audiobooks and can bookmark, though again with no hands-on I haven't a clue at how well it does any of this.
You should probably download the manual from Cowon and check for yourself.
Tell me there an MP3 player that can bookmark and has Bluetooth. All the Creative MP3 players I've owned (Nano ZenV Mosaic) have great bookmarking capibilites but no bluetooth. I hate all the cords. I'm hooked on audiobooks--Audible, Netlibrary, Overdrive you name it so bookmarking is a must. I love the bluetooth feature on my Dell and iPhone. Though I've searched, I haven't found one yet. There must ba a bluetooth enabled MP3 with very good bookmarking somewhere. Any ideas?
