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 
rackmount.
