I'm sitting here with an unopened Sony Walkman X series. I'm also sitting here with a Samsung i780 Winmo phone which I fancy changing. I'm tempted to return the X series and put the money towards a sim-free HTC Hero but what I'm not sure on is how good, or bad, Android phones are for mp3 and videos? Obviously it won't be quite as good as a dedicated mp3 player but any opinions on it would be good. Thanks.
