Sheeeet! I will trade you 3 PM G4s for your mini.
BTW, why does the wow factor fade so fast on a mini? It couldn't be any worse than my air.
I find the whole "mini" thing boring. Do I need an i7 to do my work, maybe yes. Even with the latest mini, it will not cut it for my work. I need workstation class gfx card which the mini doesn't have. Even my quad benches less but I have lot of love for it.
I find the latest iterations of OSX boring, like there is no life. Fancy, yes. More focus on cloud apps, games which I am not really fond of and inclined to do.
I do CAD work on the powermac and fancy OS is not what I need. A mac pro maybe, but I feel that it is an overkill.
My philosopy in life is that, the simpler we live the better. I need just "enough" horsepower, not too much not too little. And the powermac serves it right on the spot with what I do. It is easier to work with, change HDD's or upgrade it, it has an optical drive, DVI output, FW800/400, Bluetooth and Airport, expansion slots, almost anything that a mac pro can offer, except for the number of drive bays a mac pro has.
Consider how hard it is to upgrade a hard disk on a mini? On a power mac it is easy, flip a door and everything is there, easily accessible.
