I use one every day, mainly doing RoR development. I also have SQL Developer connected to oracle for most of the day; seems more responsive than my MBP tbh, I think it might be due to the SSD. I also use it for image editing/gfx work. The only time the performance has been noticeable has been installing apps via homebrew. Compilation is — obviously — slower than my MBP, but honestly it's not so slow that it'd worry anyone. Unless you're compiling a lot of stuff, all the time, you're not gonna notice. It's my primary dev machine and I love it. I heartily recommend it. And to reiterate some of the recommendations; get the 4gig of ram. I'd also recommend the 11" over the 13". I mean, if you're gonna get a small laptop, you should get the smallest one you can comfortably use. I hook mine up to an external monitor + mouse + keyboard. It's sweeeeet.
