Wow. I was using CarbonEmacs 22.3 till now, so I'm not sure if it's the switch from CarbonEmacs or just v23, but startup is about 1-2 seconds now instead of 5-10 (2ghz Core Duo "Yonah"). Either way, I'm sold!
Thanks for that link. I spent some time late last night comparing this new pure Emacs release with Aquamacs. I have been a happy Aquamacs user for a long time but I will probably switch because of the faster startup times and cleaner looking interface. When Aquamacs is released with an update, I would like easier options for simplifying the look and feel (e.g., having to hide the button bar, etc.)
BTW, really off topic, but does anyone know how to bind the speedbar to the main frame window instead of being in a separate frame window?
As a tip, if you enjoy quick startup times, you might want to try running emacs in daemon mode. Just fire up a emacs --daemon instance, and you can then use emacsclient to instantly connect to it.
Thanks, both of you. :-) The version up there now works with 10.5, according to holygoat (thanks to the magic "-mmacosx-version-min=10.5" compiler flag).
