Via to offer one-chip Wi-Fi: It's not precisely the holy grail, but putting Wi-Fi's radio, baseband processor, and MAC on a single chip does reduce power consumption, signal loss, and physical space, not to mention manufacturing processes.
Gigabit Ethernet continues to pace Wi-Fi: both are benefitting from enormous competition, and have become nearly standard on many computer models. All of Apple's professional systems now have at least one gigabit Ethernet port, and all high-end models except the server line have 802.11g slots.
