@bitcoinporn - The only thing I've purchased so far was a AMD 5670 for $59.  It gets around 86 Mh/s.  I also mine with my GeForce GTX470, which computes at the same rate as the 5670.  I've generated 2 BTC in the last 1 1/2 months :-/

@yellowcar - Good point.  But when you're unemployed, you begin looking at income generating options you'd never consider while employed.  And the longer the unemployment lasts, the more options one considers.  This is a poor vector of income for the unemployed - actually, I understated the point - this is an extremely poor vector of income for the unemployed.
