Ready to order, actually been putting it off. I was all set to with a base i5 27", now I see the older refurb 24" with 2.93 are going for a nice price. I'll use it for basic internet, iwork, and GB, will likely upgrade to Logic in the future. I will not be doing any intense recording. Backing tracks, few guitar parts. Likely never recording nothing more than my Duet can handle at once. Do I save the $ and go for the smaller refurb or?
