802.11g supports 802.11b and 802.11g at the same time. I consider a sort
of Auto Negotiation for wireless. 802.11g is prestandard, but several
vendors are pushing versions based on the draft, and should be fully
compliant with a firmware upgrade. Caveat Emptor.

Why would you buy 802.11g over 802.11b? Speed (and geek appeal). Since it
is prestandard, expect to do more tweaking and expect to pay more. I read
a review of Buffalo's 802.11g AP on Tom's Hardware and they saw realistic
throughput of +20Mbps to a client. If you are happy with sharing 11Mbps
between your wireless clients, there may be no reason to upgrade. If you
need a slight speed boost, you might consider running more than 1 access
point on different channels. The specs say you can run 3 APs in the same
area with no problems - on channels 1,6, and 11. I have heard of people
running 4 APs to get a speed edge (1,4,7,11).

Keep in mind that you should definitely check about Linux driver support
for any .11g cards, since they are so new.
