[Retra]

Most modern laptops are completely comparable in terms of hardware and software capabilities, so long as you aren't trying to do top-end gaming and super-computing. Administration is not significantly less painful on any one of them.

This machine feels pleasant to use. It doesn't frustrate me or get in my way. (Unless I'm using finder or other awful OS X programs, but I'm not afraid of the terminal, so I just don't use those.)
