Another attempt sony has of trying to apply real-life computer process to their hardware. With the PS2, it was supposedly illegal in some countries because it could be used as a missle guidance system.
To put it plain & simple....complicated computations can be done on it. Great, wonderful.....but any computer with the same or equal processing power could do it. Hell, the 360 can probably do the same damn thing & would be easier to program to do so, too. Or even better....how about a PC built with the twice the specs of a PS3....shouldn't cost more than $2000....that's a drop in the bucket for medical equipment prices.
So in summary, whoop-de-sh*t.
....besides. a PS3 can't cure cancer if it's still collecting dust at Wal-Mart while everybody's buying up all the 360s & Wiis.
