I'm still using my old, round airport extreme and was advised by an apple rep to upgrade to the newer, square ones. He says its five times faster. But really, for $180, does that make much of a difference. Videos play fine, email loads fast enough, nintendo wii hooks up ok. Doesn't sound like I would get much of a boost from a newer one? Am I missing something or do you guys agree, and if it ain't broke.....
