Just finished copying a few files. Bluetooth works well. Very easy to set up in windows 7. The only thing you need to do is enable a certain setting on the phone for a couple minutes and provided you have a bluetooth card on your computer, you can transfer files. I didn't bother setting up USB since I have bluetooth. The other thing you can do is listen to music (and I think video works too) that is stored on the phone through computer speakers. (This is kind of awesome if you have a HDMI cable for your computer, but not for the phone.) I'm actually not sure if a HDMI cable is available for this phone that works, but in any case you don't need one if you have bluetooth and a hdmi card in your computer. I was disappointed to learn that flac files do not work on this phone as of yet. However, I did copy a blu ray rip mkv file and the video and sound play flawlessly. Works really well with a headset. MP3's also play really nice. No skipping.
