@Charles: I haven't even tried mine with headphones yet ... odd ... the volume of the speakers on the 920 and the Surface are both way too low for me. Not sure if I'm old and going deaf, or if it's really bad. They are basically useless unless you have complete silence, IMO. I plug mine into an external portable amp to listen to stuff in the shower.
I like the yellow model ... good choice. It stands out nicely, easy to find.
