11a dead? We'll see. I think some people haven't (/m10 for example- "I also don't see an IT Dept wanting to explain to users why they must use THIS card in THIS area but not in that, and why THIS card doesn't work in THIS MACHINE or at THAT clients facilities.
") quite grasped what the new product plans of people like Proxim and so on are.

The huge cost of upgrading simply doesn't apply. If you buy a Centrino mark 2 notebook, it will, quite simply, work on 11a, 11b and 11g. Intel has held off including g simply because of the dispute on ratification. The question of "which card?" won't be asked.

The same applies to access points. Proxim (and most others) are planning multi-standard. Why wouldn't they? Today, you have to choose; tomorrow, you may not be able to; you'll get a dual standard access point, which will include g and a, thus covering all three.
