The specs for the s tablet say that WMA is a supported file type yet they do not play! There is a school of thought that this has something to do with copy protection but I'm not sure I subscribe to this as I cannot believe that every music file i have is copy protected from CD. If anyone (including Sony has an answer a quick response/fix would be appriciated as i have an option to change my s tablet to an iPad within a month and i am thinking this may be the best option as at least you can take your own music form the your own iTunes library.
