Latitude D630 + Merlin S620??

Hey everyone,

I am considering buying a latitude D630 for work(I am a field tech) because the laptop they gave me is absolutely terrible.  Anyways, they gave me this Merlin S620 Wireless internet card from Sprint.  I would like to hear from anyone if they have any experience with this card and the latitude series laptops.  I've been reading how the Merlin S620 has been known to have some compatibility issues with certain laptops and I don't want to waste my time and money if I can't get the two to work.  Any insight would be greatly appreciated, thanks.
