Off topic: I cannot imagine for one second that Ubuntu through whatever hack is required to run natively on a macbook is a better user experience than OSX itself. I get a lot of the legitimate mac bashing that goes on (expensive hardware, elitist culture, etc etc) but the OSX gripes baffle me.
I'm typing this on an early 2009 macbook my alma mater handed me freshman year. It started with Leopard and is now running Yosemite. It has a unix shell, it has vim, it has a compile toolchain (clang via xcode and gcc via homebrew), it has git...it even has x11. OSX is unix, and a darn good one. Not only that it came preloaded to edit your gnar vids from your snowboard go pro.
Back on topic, the Surface Pro 3 is a great little machine. Got one for my daughter for her graduation present, as she didn't want to learn mac or droid and wanted something to replace her aging laptop. She takes notes with the pen in her own handwriting. The keyboard/cover/thing is actually a decent keyboard - the trackpad on it is kind of meh, however. I just wish the price points were a little lower, but that's just cos I'm a cheapskate.
