I have no illusion about my hardware (i7-2600S @ 2.8 GHz and nVidvia GT 440), and understand that it is an ASIC game. But I didn't realize that 100+ hours of 25 Mh/s (indeed M, i.e. 25000 khs) isn't even worth a hundert millions of a Bitcoin anymore. I just wanted to get ANYTHING on my empty ewallet without having to exchange €
Sorry to say that, but you probably have to mine at least a month with 25Mh/s to get a some mBTC (~0.00042077 BTC/Month on 25 Mh/s).
And the previous Poster are right, deepbit must find a block to pay something out. Maybe use a bigger Mining Pool.
