The Return of Emacs
Getting the fonts right has got Emacs back to my desktop. Since I got the Mac (hey, that was October 2003, time flies!) I was using it occasionally to edit my encrypted passwords file with crypt++.el, and some editing here and there, but the font rendering made it kind of ugly and in consequence didn't fire it up often.
I was mainly flirting with SubEthaEdit, or TextMate for quick scripting, with vi in the command-line as usual. Regular programming at work, or playing around with my personal projects, went to Eclipse.
Although I don't have the same control over Eclipse than I have over Emacs (not to mention the list of available modes), and I miss a lot the smart M-q, Eclipse is an IDE I like, and its support for Java is superb. Only it eats too memory for these 512MB, so I need to keep the number of open applications small.
For Perl, Python, reStructuredText, and some other stuff my editor of choice now is Emacs again.
Talking about SubEthaEdit, I saw the other day an interesting usage: people at some Python Conference were taking notes in parallel. Cool!
By the way, with the configuration I came up with a couple of days ago most glyphs were OK, but then I noticed a few keys didn't work properly. Thanks to news:gnu.emacs I could figure out the correct value for mac-keyboard-text-encoding is kTextEncodingMacRoman.
