There's a saying in the tech-world: "Innovate or Die".
You all just want Apple to keep playing the same old tune, JUST because they released a product THIRTEEN YEARS AGO (the G5 Tower), that you liked.
And if you think the Cylindrical Mac Pro wasn't already WELL in the works when Steve exited this plane of existence, you have NO idea how long product design lifecycles are, ESPECIALLY for something like THAT!!! In fact, the cylindrical Mac Pro has "Steve" written ALL over it...
I guess Steve didn't learn from the flop of the G4 Cube then. Towers and replaceable components still make sense. Would you buy a car that needed to be completely replaced when the tires wear out? Or needed to be completely taken apart to fill the gas tank? That's the crap Apple is pulling now with their "pro" machines"
