Thanks for the very clear explanation. It's a subject I (obviously) knew
nothing about.

I managed to return the card on the basis that it was mis-sold (I had
originally explained what laptop it was for and requested confirmation that
it was compatible). I asked the salesman I was returning the card to if all
the laptops he sold used Expresscard. He said they did. I asked how many
Expresscard devices they had in stock: none apparently. So unless they are
actually selling dual-format systems such as those you mention, they are in
for a number of other errors such as mine.

Thanks to all who took the time to advise me.
