I'm about to buy a new Zen Micro for my daughter. She has her music files stored on WMP 10, some of which were transferred from I-Tunes. I have only USB 1.0 on the PC. Two questions - is there any compatibility issue with transferring the files from Media Player to the Zen?? Will the original I-Tunes files present a transfer problem or wil they have been converted at the switch to MP10? Any thoughts advice most welcome..............thanks.
