Why would you want wireless in a desktop anyway?
Because I can't drill holes in floors and walls that I don't own in order to run cables. I know others who only have Internet access via wireless connections. Neither one of these scenarios are that obscure.
I'm just running a 50 foot Cat 6 cable across the first floor, up the stairs, and across the hall to the room where this desktop is. No drilling required. Also the wireless interference around here is horrible. Too many people who know just enough to switch to 802.11n but not enough to reduce transmit power or check for interference *sigh*
