Joel on TextMate
Joel Spolsky (who started his career at Microsoft as a manager on the Excel team) has been writing some recent longer blog posts on a MacBook Pro in TextMate using Markdown. He describes the process in a recent entry. He calls it a “surprisingly good experience.”
He goes on to gripe about anti-aliasing quality (FWIW, that’s explained here), and beachballing from dropped wifi connections (which I’ve never experienced, maybe it’s an early Intel thing?).
