As has been said before in other threads the big advantage of 802.11g on PPC is that if you are sharing access with say a laptop that has 802.11g then you can still get the fast access with the laptop.
If you have PPC with 802.11b, then your wireless network will slow down to 802.11b speeds for all other devices that are accessing the net.
I think 802.11g for PPC is great - provided of course the power consumption is not much higher.
