Hmmm, let's see.
The Sheeva Plug was $99.00
The USB Audio subsystem I had to buy for it was $79.00
So, $178.00 divided by 96000 samples/sec
Let's see how that scales using a USRP1 and a "mildly pimped out" PC
USRP1 is $700
PC is probably another $700
So, $1400.00 divided by 8megasamples/sec
That's roughly 0.02cents/sample/sec
The USRP1 + PC is roughly an order-of-magnitude better value, when
looked at in that way.
