Hi, Hopefully this helps those on the fence. I was really reticent about buying this machine, but found one on eBay in great shape and decided to give it a try. So happy I did. I got the base model (1.1, 256gig) in space grey, and it looks awesome. I use the computer mainly for business, I run a consulting firm in New York City, and that involves a whole lot of Microsoft office, pdfs, and web browsing. I should also point out that it involves a lot of travel (including local travel) as well. Not only have never had a performance issue whatsoever. In fact, the battery life has been surprisingly good -- I average about six hours of heavy use (practically no sleep). On most days, I charge it overnight and then when I get home around 7:00 PM I have about 30% left. This coming from a 2013 retina macbook pro 13". As to the single port issue, it's actually never been a problem. I bought this handy adapter: http://www.amazon.com/gp/product/B015Z7XE0A?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00 And the reality is that I didn't really use the ports I had all that much. Once I realized that what this computers drawbacks were actually not applicable to my day-to-day life, I never thought about what's missing. Instead, I now have the lightest and in some ways the best Mac I've ever owned. I may be in the minority but the keyboard is great. This is especially true if you touch-type. This machine is so much better in the real world (at least my real world) than it is on paper, I encourage everyone who is put off by the port issue, battery life and theoretical performance to give it a try. The only downside is that now everyone who works at the firm wants one, and that's definitely not in our IT budget for the year.
