That's pretty slick, but do you think it would work in a PC?
only in a pc laptop... unless you have a pcmcia slot on your pc
This isnt' a PCMCIA card... it's compact flash. You can get a PCMCIA adapter for it, or it might even come with one, but it isn't required to function.
You can use this in a desktop PC as long as you have a CompactFlash slot, either onboard or as a reader.
The wireless I'm not 100% sure about, but the card itself will certainly work. And I have no reason to think why the wireless wouldn't as well.
