Just thought I would drop you a line and update you on the progress of using the Mattel JuiceBox with a custome uClinux kernel. There is even an interesting project to combine a Mattel JuiceBox and the (now defunct) CueCat barcode reader. A Cheap barcode data collector! There is also a project to add a USB Type-B connector to the JuiceBox allowing it to be used as a USB peripheral. A Cheap portable media player with USB interface! Additional Information can be found on the messageboard and WIKI
