Just reading about all the things you could do with the ExpressCard. I feel 17 is too big, so will probably get the 15 but also feel I am missing out on all the potential uses with the ExpressCard. Not that I have any in mind right now, except perhaps using eSATA, which is faster than FW800. Apple took the ExpressCard away last year on the 15, but previously it was there. Doesn't seem to make sense for them to take it away?? They put back FW on the 13, why not put back ExpressCard on the 15?
