i disagree with the vulnerability issue, as xp has enough protection as i am running that. and that's a rare case to have an attack dude, idk what your browsing but it should be safe. slow? how fast do you need internet explorer to be? jesus christ dude, get with the technology here. video streaming? i'm streaming just fine on this laptop and it's not exactly the fastest cpu to get. i know, but it gets the job done, why send him out on money binge when he didn't state, that's why i put that he didnt' specify.
it's not a complete waste dude, i'd say find a cheap part from ebay, it should be easy. plus video streaming? i got something to say to that. since i'm an expert on building computers. what could you possibly be watching? i mean i have a 1920x1200 screen and i bet it's better then yours. what is the standard like 1080p right? i mean seriously, it's how you choose your hardware man. not the latest and the greatest and some laptops can't even do this resolution, (but props goes to dell for creating a 3200,1800 screen) i got to admit i only upgrade when resolutions come out, it's the best thing to do, and i been drooling over it ever since it came out, can't wait to get it. and this laptop is really really freaking old. and it's fast enough for me, in fact, i didn't even upgrade the 4,200 rpm hard drive cause i didn't need it.
i really think your sending this guy in a money binge, that's all i got to say. and i beg to differ it's being maxed out, i mean even my 2.1 ghz sits idle while browsing the internet so i don't know what your talking about man. whatever your smoking i want some of that delusional stuff.
