A cylinder that's 6.6" in diameter and 10" tall!!! That's pretty damn small - definitely an amazing design, a desktop computer with ample power, that's the size of two Kleenex boxes stacked up. Wow.
I sill want a new 17" MBP, though... I expect that at some point soon, LCD panel makers will come up with a 17" retina display, then Apple will bring the big boy back to the lineup.
