I'd suggest simply waiting until the new models are released and buying what you need/want then, rather than wasting time and energy on buying and subsequently selling a mini just now. The MBP is an excellent computer, fast, powerful, great performance, superb screen, and attractive aesthetics. Wait for the new one; if you don't like it, go for a refurb, quite likely there will be generous discounts on them by then.
Cheers
