Seconded. I used it for Java/web development for a year after switching from Linux and was delighted with the ergonomics of use. The multi-desktop swiping easily compensates for multiple monitors. The light weight and huge battery life let me work anywhere, from cafes to park benches to various spots around the office, for an entire workday. The performance was more than enough for 99% of the time. I valued the comfort od use much more than that remaining 1%.

I only switched to a new MBP when 8GB RAM became too tight for my work.
