I would only buy one of these if I had Mac-exclusive apps that absolutely had to have speed right at my desktop, such as making movies or retouching lots of photos or doing graphic design. Pretty much everything else can be done either on cheaper Linux boxes or in some form of cloud hosting environs. In fact, I’d go so far as to make my desktop a little slower to self-enforce a work-ethos to constantly figure out how to offload the computation to other, cheaper-to-run CPUs/clusters/cloud formations.
