In my opinion, if you prefer Linux over OS X, you should take a look at Dell XPS 13 Ultrabook.
Yeah? I haven't looked at one in person for ages, and don't see any at all in the Apple site pictures, so I'm guessing that you just tap the trackpad? But what if you want to right click to do something, or middle click to paste some text?
alternatively (and by default), a two-finger tap is a "right click".
not sure about a middle click.
Both the Dell and Apple refurb stores should be your first port of call.
