I wish it was EVDO maybe someday.

I need it for updating firmware on old Ricoh copiers and printers. They use a proprietary (or so they say) 4MB card and there is a really old outdated program that writes the file to the card which does not work with a USB reader. I don't need to do it very much but I don't want to have to carry two laptops around.

Also I like to have the slot incase I do need to get some kind of high speed wireless.
