The xbox2 will also be obsolete within a year. That's called progress.
It won't be a year from now, though, as it doesn't even exist yet. By
the time it comes to market everything else will be faster, and it won't
look so hot. If I base today's DSP board on TI's chips planned for 2
years time, it will also appear to have a better cost/performance ratio.
:-) People don't want a pile of xbox2s to run a telco. They want neat,
compact, manageable systems. Packaging is important. One disadvantage of
a DSP card separate from am E1 card is you can't get 2 PCI cards in a 1U
