Now imagine this with thousands of PCs out there playing the lotto every second. Just because you have a quad-core system churning 2,400 khash/s doesn't mean you are going to win every time. It makes your odds better of course, but by no means is it a sure thing just because of the raw CPU power you have. Ask the people at this forum who are running this on a server farm (like myself) and you'll see. I'm churning 10,000 khash/s on one of my systems (6 cpu) and it hasn't won a single block yet

I'm not bitter though, it proves to me that the system is being fair in the block generation, so I'm happy actually.
This is a good point. My weaker PC is barely squeaking out 1,000 khash/s on two cores, and has netted me 100 coins in less than 48 hours. My server, on the other, hitting closer to 1,200 khash/s on two cores (not a huge bump, but still more), and has been running for about 12 hours longer than the other and has netted me 0 coins. So, like knightmb said... there's hope still.
