Wirelesslessness

[desperance]

Hmph. I appear to have purchased a desktop computer without a wireless LAN card. *boggles at the thought of a desktop computer without a wireless LAN card*

So tell me, O internets: is there a performance hit associated with wireless USB network adapters, as against an internal card? 'Cos, you know. Plugging in a USB is much less scary than opening up a box and installing a card. Which I have never done.
