SanDisk's Sansa Connect MP3 player won the Best of Show award for MP3 Players at this years Consume Electronics Show. The device runs the Linux operating system and the application stack is all built on Mono.
Miguel de Icaza of Mono reports that they have been working with the Zing engineers for four or five months to improve Mono's performance of the ARM processor, which is used in the Sansa Connect.
Zing is revealing anything about the architecture, so there is some speculation as to how it actually works and what other technologies are involved. For example, Ross Burton asks, " Does it use SDL, GTK+, X, or something totally different?"
