Not meaning to ThreadJack this, but people "Holding out for 802.11g" may be holding out for a LONG time. At best, you'll see it in a a/b/g combo card, but my belief is that 'g' will not come about as much as many of us originally hoped before it was finalized/ratified in June '03.
I'd hold out for an a+b card, now - and I have a b/g wifi home network... just my guess, of course.
