omg please dont do SONY!
im tellin youfrom experience
i have the sony walkman and it broke after a weak and the thing wasnt cheap either . on top of that i have the sony ericson slider phone which is awesome but it freezes and theres just alot of issues .
sony's are so cool to look at there awesome but they dont work well .

get an ipod nano there around the same price and they work a hell of a lot better - only the nano though because they last all the other apple ipods freeze and break lol
