As of August 2013, I am very well adapted to the MacBook Pro, and do essentially all of my work there except for Linux audio software work, which still requires a real Linux desktop machine. (I could dual boot, but would rather not due to insufficient disk space and the inevitable headbutts that would ensue.)
My primary working tools on the MacBook Pro are Carbon Emacs, Octave, Faust, Xcode developer tools, Logic Pro X, and countless MacPorts packages (installs logged below in later sections).
If VMware Fusion ever becomes usable for Fedora Linux audio work (i.e., no constant xruns from JACK), and if SSD disk sizes roughly double again, I'll actually be able to do everything I am currently doing on the MacBook Pro alone.
