This thread has me wanting an X5000. I'm typign this on my SAM440ep-Flex, and I intend to go for a Tabor when it lands, but an X5000 would be something else.
It is a shame that the Xena co-processor is not utilized by software (at all?) so far. Are there programming APIs for accessing the device, or is it a matter of going directly to the hardware. (Wondering if that's why there's not any, say, Mandelbrot generators for the thing.)
As re: MorhpOS on Macs, many disagree I am aware, but there seems to be something said for supporting the core "Amiga" OS vs. derivatives. More support, more potential for future developments, less fracturing. But, of course, just my opinion.
