As a mac user, who needs a network? I went to my brother's house, who had a cable modem plugged into his wireless access point (802.11g), turned on my laptop and turned my computer (and his 2 machines) into wireless servers in about 5 seconds. He and I could share files, music, anything in no time at all. My tech person at work was amazed at how easy our wireless iBook found our wireless system. It took about 30 seconds to set up- and neither she nor I had done it before. Signed, Loving my Mac (I'm not concerned that not everyone has one- they'll figure it out someday)
