Gameboy Advance Users to Get Bluetooth Internet
AEton writes "According to this Extremetech article, X-Tra Fun has developed a Bluetooth module for the Gameboy Advance which is expected to ship by Christmas 2003. The $49 module includes Bluetooth connectivity, although a cellphone or other Bluetooth device with Internet access is required to use the Internet, and it comes with an embedded eCos Linux kernel with a Web browser and 255 pages' worth of cache. A $99 upgrade adds a Secure Digital card slot and a dongle!"
eCos is an embedded kernel that was developed by Cygnus, now owned by Red Hat. However, it is NOT a Linux kernel (although the userland tools are probably all GNU).

There is another Internet OS that currently is being ported to the GBA called Contiki. It currently features a lot of what it to be expected of a modern OS such as multitasking, TCP/IP support, web browser, screensavers, etc. Still, it only requires no more than 50k and ought to be a lot faster than eCos.
