The non-TB version is nice with a lower power CPU and a higher capacity battery, BUT only has 2 ports instead of 4, which is nothing short of absurd. They really screwed up on this front IMO.
When out and about, when do you need 3? Can't ever recall seeing someone at a coffee shop, conference, etc needing 3 USBs.
As I speak I'm using magsafe + thunderbolt2 + HDMI + 2 USB, 1 for peripherals and the other for playing back video.
