The Retina Macbook pro 13", with the keyboard from a ThinkPad X60.
Seriously, the only thing stopping me from switching to a macbook for everything I do is the lack of an intact ins/del/home/end/pgup/pgdn block sitting above the backspace key. Every one of those keys has an equivalent, but every one requires two hands to do. Since you usually (in windows at least) chord those keys with a second hand anyway, you have to make the mother of all hand contortions to do something as simple as a ctrl+home to get to the top of a document.
It's a shame. They make such good laptops, but their keyboard scheme is just a frustration bomb.
Second place: A ThinkPad X60 with this year's CPU, memory capacity and SSD.
Third place (and thus, fallback): A ThinkPad X60 for $150 of eBay, with maxed (4gb) memory and 512gb SSD.
