Express Card

I have the old 15 inch powerbook and live in the country in Spain. Not having a direct telephone line, I have to use the PCMCIA 3G vodafone mobile solution for getting on to the internet. I only have 2 neighbours and they too do not have telephone lines). I have just purchased the 15 inch Macbook pro... and notice that it does not have the PCMCIA slot any more.I must admit I thought I was just buying an updated version of the old system..... I have promised my daughter the old notebook. Is there anything I can do... Is there an adaptor to go from Express card to PCMCIA... otherwise I am screwed??!! Regards, Stuart
