I want to buy an old laptop so I dont have to sit in my bedroom every time I need to use the internet or write a document. I have been looking around and they all seem so expensive! Does any one know where I can get one cheap. I dont really want to spend more then £100 to £150. Thanks P.S How would I set it up so I can browse the internet, wirelessly, useing my broadband modem attached to my PC. Could I use a blue-tooth card?
