Hello, I need a new laptop and I'm not quite sure where to start because I know nothing about computers. I know that I need something that is very durable because I move my laptop a lot. I do a lot of music downloading, so I guess I need something with plenty of memory, I'm not quite sure. I was reading that it was good to get an external hardrive to add on to the internal hardrive, but I don't know if that's hard to do. I was thinking of going through Dell, but not sure if that is the best bet. If anyone can give me some tips and recommendations, that would be great! Thank You
