It seems many say that, e.g., G is backward compatible with A, B. If so, why not just make cards with G alone? That would cover A, B, too, wouldn't it? Why need AG, BG, ABG at all? Sorry if I'm sounding dumb in asking...

802.11b is backwards compatible with 802.11b but not with 802.11a as the latter uses different frequency (5GHz instead of 2,4GHz) so its necessary to explicitly point out if a band works or not.
Theres not much trouble in listing it and its also sanctioned by WiFi alliance so its the easy way to let people know if what they intend to buy is going to work. Not everybody has to know that their b device is going to work with g router just like you didnt know that an a device is not gonna work with g router.
