Be aware that those Orinoco cards only support WEP WiFi encryption which is trivial to crack. I think there are cards/ways to use WPA/WPA2 with a 1200, but I don't know (probably those USB dongles?). If security is no issue however (i.e. you need make your entire LAN less secure to use it), then those Orinoco cards are a safe bet. I think I used one of those Dell True Mobile cards too on my 1200 ages ago.
