If you took a small sip of the kool aid you would then be aware that the recent Mac mini hardware refresh (specifically the upgrade to the NVIDIA GeForce 9400M) has been thoughtfully positioned for the future. At $599 US it's the cheapest retail entry fee into the cult. With OpenCL coming this fall alongside Snow Leopard, and this recent article about the 9400M, I think these lil' Core 2 Duo boxes will be doing some heavy lifting.
