The new networking thing that we are playing with is the Apple Airport Express. I bought 3 of these things to extend the wireless network (Linksys WRT54GS's), in our home as well as being able to send music that is on the computers to the home theater.
We are strictly a Mac Family household. I have the G5 in my office, a G4 in the downstairs family room, G3 in the upstairs den, my wife & I both have PowerBooks, and when my daughter is home she has her iBook. All wireless.
No WEP crap here either, like Mark_AR were living the good life in rural America so no penalty to the network.
