With the new design, many ports and features were eliminated/changed. (i.e. No FireWire port on the MacBook, Display Ports changed to Mini, etc.) But weird things is... what do you use for express card slot? It must be necessary with something, because Apple eliminated a modem port but left this thing on there. (Not that the two are relevant, just curious why they didn't just eliminate a function people rarely use. Or am I the only one that don't know what it is =P) Well, it's not just Apple that has an express card slot, Now I realize that most of the notebooks I have seen and used DO come with express card slot of some sort. (I think, right?) I don't know why I didn't bother to wonder what an express card was or even cared to use one. What is it? And what are some ideas that I could use it for?
