No, the "old" PCMCIA is actualy something *different*.  I think many (most?) 
laptops (at least "PC" types), do use an *internal* mini-pci card for the 
wireless, but it is "deep" inside and not normally "end-user" accessable -- eg 
it is somewhat non-trivial to swap in a different wireless card.  It is really 
a kind of motherboard daughter board (it uses a connector something like the 
DIMM memory slots).
