I sent in a rebate to PCUSA, for this same card reader) near the end of January and haven't heard a thing yet. I won't be surprised if I get stiffed on this one, because PCUSA is not a company that needs a good reputation. Still, it hasn't been long enough yet to draw a conclusion. Just a warning.
It's a nice card reader. Better looking than the other ones I've seen.
For the record, it doesn't support XD.
