hey. i've got some questions. i've got this hp pavilion ze4900 laptop. it's got 40gig of memory and 256 megs of ram (or something like that). and now, with all of our big ass photographs (sorry, none are of big asses, and those that are of asses will not be posted ), are filling up our memory. it's also getting super slow (can that be related to having a ton of pics stored on here?). what are my options? can i upgrade the ram and hard-drive space easily and cheap? i'd like to get an apple, since they're good for artwork, so i'm thinking of leasing one in a few months when i'm in a better financial position. is that a better option?
