I second this. I'm using a just-refreshed 12" Retina MacBook ‘toy’ (BTO m7/8GB/512GB) and it is an utterly perfect, ‘nervous’ little machine that suits my varied computing needs perfectly (local databases, spreadsheets, data exploration, symbolic mathematics in Mathematica, general productivity word-processing/email and assorted browsing & multimedia). This is a machine that deserves respect.
