I may reverse course on this, but this afternoon I ordered a maxed out refurbished MBA from Apple, for pickup at my local store later this week. The i7/8GB/512GB one. It wasn't any kind of super-smoking deal, but it was a discounted price. It is definitely *not* on my list of things I actually, you know, need. But I've been wanting one. As much as I like this 11" 2013 MBA (heck, I'm sitting here on the sofa using it on my lap to write this), I've come to like the 13" screen size better from using that size (PCs and Macbooks) at work, and as a photographer I've always regretted the lack of an SD card slot on this 11" MBA.
So I have a few days pre-delivery to reconsider whether I'm okay with spending that much for a secondary/travel computer. I haven't seen any great deals on the 2.2GHz i7 13" MBAs, whether new, refurbished, or used, and I've been researching several sources for awhile including Craigslist. And TBH, if I'm going to get another MBA I think I'd regret not maxing out the specs.
Or maybe I should learn to tear down and rebuild Macbook Airs, like the impressive Macdctr? Oddly enough, I'm kind of interested - but afraid I would do more damage than good if I tried.
