The 800/810 are identical. The only difference is the software. One uses SonicStage and Atrac, the other is drag and drop. I'm not sure about the differences between the 720/820 other than the 820 comes with Bluetooth, which I have no need for, but as the 729 isn't available in the UK - I bought the 829.
