So my mom's old Pentium III finally crapped out and died, and she went out and bought this HP zE2401xt laptop for 550. It was on sale at Circuit City. The laptop is advertised with 512mb RAM, 60GB hard drive, blah blah blah. Anyways, when I opened the properties on My Computer I noticed that it said 384mb RAM. My mom thinks she got ripped off and wants to attack the store later today; I'm thinking that the rest of memory is saved for the video card or somethin', but I'm not sure. Any thoughts?
