Apple announced its new LCD-based iMac line of desktop computers today which feature antennas that run from its unique base up through an articulated arm into the sides of the flatscreen display. Apple pioneered the use of 802.11b in its AirPort system, and its also innovative in how it incorporates antennas into the products themselves. Of course, this backfires in the case of the Titanium PowerBook, which has such good RF blocking on its innards that the two antennas built into it don't radiate or receive as much as they should.
