I ordered one of the new AirPort Extremes earlier this week, and it arrived yesterday… holy crap having wireless speeds the same as 100BaseT ethernet is awesome. 😀 It was an absolute cinch to set up, too… I ran through configuring it all at work, put it into bridging mode (since I’m still using my existing network as well, I don’t need it doing any routing), plugged it in when I got home, and BOOM. Über speeds.
My parents are using my old PowerBook, so I’ve got two wireless networks… the 802.11g one from the old AirPort setup, and the new Extreme is set to 5GHz 802.11n-only mode for just my MacBook Pro. Works very nicely. 🙂
