I'm trying to decide between a low-end Mac Pro and a high-end iMac. The iMac would provide more bang for the buck, but the MacRumors buying guide cautions against buying one now. However, the only CPU change in the next few months will be a minor Haswell refresh, since Broadwell is delayed until next year. I assume that Apple will also update to TB2, which I don't really need, and I don't expect any changes on the internal storage or video card front. So the current (late 2013) iMac makes sense. Am I missing anything? TIA.
