Mark Pilgrim, noted long-time Apple fan, has recently switched to Linux which has predictably earned him the ire of the Apple zealots. With 90+ venom filled comments, and counting, there's enough material for an entire Ph.D. thesis in cult-like behavior tied up in that thread.

BTW, just upgraded the laptop to Dapper (aka 6.06 LTS) and it works like a charm, and no, this is not a dual-boot: Linux is the only operating system installed.
