Husband has heard Dell are good I have heard otherwise I get bamboozled by computer speak so please if possible could the answers give me as much detail as possible eg RAM, Processor, Extra features and also where can I get a simple program or book to teach me the basics I mostly use publisher, word, Excel and photo-shop but only use half the features as I don't understand them. I have windows XP on my desktop computer will I have trouble converting to Windows 7?
