Ok all, I'm currently a PC user looking at getting a PM G5 (not really a "switcher," as I plan to use both... I'm just a big time technology buff ). I don't really need dual processors. Thus, looking at the Apple store, I find the single 1.8 Ghz refurbs they have on sale for 1599 right now VERY tempting. The only thing holding me back is all the rumors of new PMs being released soon. My thoughts are either A) Ill get a rev. B or B) the rev. As will become even cheaper. My worry is that the refurbs will disappear and I'll be stuck paying more, or worse, being unable to afford one at all (if for example, the rev Bs are an all dual lineup and the prices start at say 2199). So, wait, or buy now? Any advice?
