My mother is looking at purchasing a laptop. I'm looking at IBM because I've had really good luck with them. She is on a extremely small budget. All she does on the computer is browse the internet, chat on AIM and do some word processing. Would a 1.3gHz Celeron processor suit her fine? Would I see a large improvement if I moved to a centrino processor? I would like to order it tonight so please let me know ASAP. Thanks!
