I have the Sony E354- supposed to get 50 hrs. run time....but doesn't get anywhere near it. (But still gets way more than the Clip)- of course, in a test where it was just sitting on a table it might get the 50 hrs. but in the real world, the controls are very sensitive, and thus the screen is always being activated (even when you have it set on "hold")- which I'm sure has something to do with it. Great player if you don't mind the sensitive controls. I've actually got mine for sale for $50 + $15 for international Priority shipping or $6 domestic. It's barely two months old and in perfect shape.....been charged three times.
The world's foremost expert....on my own opinion!
