Apple's new Mac Pro has a replaceable socketed CPU

The new Mac Pro is truly a uniquely designed desktop unlike anything anyone has seen before. Yet, the fact that this compact computer is one of the first fully-solid state workstations in the market (meaning no moving parts), makes some potential buyers nervous.
But fear not, the most important components of the Mac Pro can be replaced and upgraded quite easily. The RAM and, most surprisingly, the CPU can be replaced if need be. The fly in the ointment is that the SSD drives and the graphics cards are permanent.
