>> Too bad. There's some useful toolset product development going on, 
but  it's wasted. I would like to see some serious competition on the

Have a look at www.rowley.co.uk

Crossworks available for ARM, and MSP430 and hopefully soon AVR. (Hint, 
hint, Rowley ;-)

I have both the ARM and the MSP430 running on Mandrake and they work a 
treat. My only gripe would be lack of USB JTAG interface. Apart from 
that, they're really good development tools.
