The Pegasos is the choice for you hands down. As a Pegasos user and owner I cay that. I've used an A1 and linux is not supported nearly as well as it is on the Pegasos II. The pegasos is now supplied and used by Freescale (Used to be the semiconductor division of Motorola) as PPC dev machines and is also a partner with IBM now with many others comming on soon. Its got masive linux support. The whole concept of the Pegasos is designed to be open to as many OS choices as possible. Its a fantastic machine.
