Two other standards designed to improve compatibility between different vendors' access points were also approved."

-less interference from bluetooth and microwaves
-more advanced modulation standard=more data in less BW.
Bad things about a:

-can use lower cost ic and materials. Testing is easier.

Repeat after me - Radio Data Rate!=Data Throughput (Score:5, Informative)
On ordinary 802.11b gear, the maximum "radio data rate" is 11Mbps. Once you account for the inherent loss in throughput because of the uncertainty of the medium (air), and the fact that the protocol was designed to accomodate this uncertainty, your actual maximum "data thoughput" is about half of that - around 5Mbps. 11Mbps 802.11b != 11Mbps throughput, it never has, it never will.
The same goes for 802.11g - the maximum radio data rate was, and _still is_ 54Mbps. However, the throughput is again slightly less than half of that, in the 20Mbps range.
The reported "change" to 802.11g to "20Mbps" media frenzy stemmed almost entirely from simply clarifying that the actual "data throughput" was about 20Mpbs, *not* that the radio data rate had changed, been knocked down, whatever.
You get roughly 20Mbps "data throughput" in a pure 802.11g network - and again, similar to 802.11b, 54Mbps 802.11g != 54Mpbs throughput.
A 4x increase in throughput using 802.11g over 802.11b is nothing to complain about. Now, if we could get Atheros 802.11g drivers for Linux, I'd be a much happier camper
