icolsuineg,
I understand the ramifications of solo mining. It may be unlikely that it may bear any serious fruit. But there is a certain amount of randomness as to who will solve the puzzle.
My thoughts are that if you have a machine running full time anyway why not solo mine on it as well? It would seem to me that consistency could be as important as TH/s. I would hesitate to say that it's useless.
That said I'm not very happy with the removal of coin generation from the 0.3.22 client with no notice of it on the web site nor the readme file. I think removing that ability removes people that have limited technical aptitude from being involved with BitCoin and will slow down it's acceptance.
My 0.02 BTC worth

Thanks for the input though,
Sam
