Hehe - it adds up over time. I've been using it for... I don't even know? And I have 1700-1800 PRE right now. This is from not trying to make the 4 PRE a day, just from actual use. I just let it sit there until it's worth a nice sum of money, until then I just like the blue screen and the maybe this will be something someday - a Google Killer or at least alternative if you will ;-)
