I've chuckled a few times in this discussion where people have been asking "Have you tried Eclipse on an SSD?" Know what makes an IDE work even better than an SSD? Being able to fit the entire thing in RAM and not have to page out all the time.
Other than the speed part, the main reason I keep using Emacs is because of the easy-to-access-remotely part of it. I've got a nice beefy Linux box at home that I can ssh into. Tmux keeps my sessions alive. Emacs lets me do all of the code editing. And the nice little Surface 3 is easy to carry around and makes a fantastic SSH terminal.
