There should be a website (there probably is this website and my googlefu is failing me in finding it) or an outstanding service department of some store, where you can just answer tons of questions/select certain options, and it will tell you "This is the computer you need!" Laptop/desktop, operating system preference, processor/hard drive/memory, size, battery life, weight, a big list of programs to tick off the ones you use, additional features, ta-da!
