Well, provided it ha a usb slot that will take a card reader, I can live without.
But virtually everything has a SD card reader now. I make a point of only using devices which take SD cards. It makes life a lot easier when everything uses the same type of memory card.
I don't really use XD now due to it being an old camera, the micro SD never comes out of my phone and CF is on my DSLR, which is pretty much the standard for that so...
