Tiger review

Mac OS X 10.4 (Tiger) is out, and you may know what that means: John Siracusa wrote another fascinating review for Ars Technica, concentrating less on the advertised features and more on interesting stuff under the hood that bodes well for the future. Among other things, Tiger includes a major revamp of Quartz Extreme that is curiously disabled in the shipping installation, and new features at the BSD level that suggest a move toward rich file metadata (a near-obsession of Siracusa's).
