With triplets, everything comes in threes. My teens got Sony Erricson w300i phones for Christmas, I use this card to drag and drop their music from our mac and the sound is incredible. To use the Mac & iTunes one needs to download music in mp3 format (tunes bought from iTunes CANNOT be converted). Then open the hard disk, open iTunes, & find the music library. Plug the phone in using the USB port and then just drag and drop songs or albums into the phone's mp3 file (seen when you open the memory stick for the phone). All the data is there and the sounds are good. The kids are no longer carrying their iPods as they have it all on one device. Access to songs is easy on the phone with no lag.
