not mining... I thought I read mining takes quite a bit of electricity costs that prohibit any real gain??? 
that depends on your cost of electricity, and how many hashs you can crank out.
it costs me about USD$ 0.30/hr or USD$7.25 per day, so as long as I make at least 1 BTC I'm coming out ahead.
At 1.6GH/sec, I can make at least 2.5BTC, so it is possible to make money
