The electronics manager at one Walmart that I called said they didn't carry this player because "we don't have a cell phone kiosk yet."
I think this is the same as the HD-A1, except for the color and the buttons are rectangular instead of circular. The remote is the worst I have ever seen. All buttons feel the same, their configuration is different for play, pause, etc. than I am used to. Its as if I purchased a Porche with a Chevy drivetrain and the steering wheel is on the right side.
