I don't know much about the ExpressCard slot, but I do gather from the wikipedia page it could be used to easily upgrade some features of my laptop.
I'm running a Dell Inspiron 1520, with absolutely no modifications. If possible, though unlikely, I'd like a faster processor, more RAM, or a better graphics card.
Is any of that possible with just the ExpressCard slot? I'd rather not have to crack open the case to make modifications.
If so, where can I buy these parts and which ones should I buy?
If not, what the heck is this slot for then?
