I use emacs 23 (alpha version). It’s still under heavy development and considered not for general consumption but you know, emacs “alpha” is like “service pack 2″ for others; it haven’t misbehave once.
One of the greatest features of this version of emacs is the multi-tty support, and it means that you can have with a single emacs server both an emacs client running in text-mode and another client running in graphic-mode.
One of the pitfalls of my emacs installation is that I load several libraries so it takes a while to start-up (not like eclipse, I mean a while like 5 seconds). It would be wonderful if emacs could somehow be ran as a daemon and then you could run your emacsclient and have instant access…
Well, it can!. Emacs has a new option –daemon that runs emacs on the background as a server, so you only need to call emacsclient. Emacs rules!
