i have been out of the states for a really long time, living on tropical islands where tech news isn't exactly the top subject. so i am coming back to the states for a visit, and wondered if anyone can give me some information about memory? for instance, what is the largest memory chip you can purchase? can i purchase a 2 gig, 4 gig or maybe even a six gig chip? and can you get it for a laptop? what is the fastest memory you can put in a laptop right now? how expensive is memory right now? i know it goes up and down pretty quickly, at least it did the last time i lived in the states. thanks for any information anyone can share. i appreciate it.
