Well, now I'm obsolete.
Not a big deal, really. My 17" G4 is plenty fast for what I'm doing right now - anything I write that's too slow for this machine probably needs to be optimised. Anything from someone else that's too slow probably has other problems and I should reconsider why I'm using it.
I can run Halo, Call of Duty, and Homeworld 2 just fine - and like I have time for more computer games!
