Got some 4 gig cards, to find that none of my readers will deal with them (great) anyway, I figure I should get one for the laptop that goes in the slot so its one less thing to lose.

My last cardbus (well, actually pcmcia it was that slow) one totally sucked, taking all the CPU and then still taking all day to transfer 2 gigs, so I really want to get one that has some speed to it rather then a cheap passive converter.

express card is an option since my T43 has a slot, just never used it.

Would be good if it could take micro sd without adapters, but I have never seen that on an internal reader and its rare as anything on USB ones as it is.
