Netgear is selling an 802.11a adapter card for $69. That’s comparable to cheap 802.11b wireless cards, even though 11a offers more bandwidth, cleaner spectrum, and better security. The large installed base of 11b cards and access points means hybrid a/b solutions will probably dominate the market for a while, but 11a is going to be more prominent than most folks realize. For Internet access, the extra bandwidth is meaningless, since most connections are far slower than even the theoreticall 11-megabit maximum of 802.11b. But for applications like sending media around the home, the 54 megabit speed of 11a is essential.
