None of the above. Get a low cost laptop. You will be a lot better served. E.g. something like this one. Just look into the Sunday ads.
With that you get a duo core processor, nice large screen, plemty of RAM, a CD/DVD reader, a big disk and better graphics. For the few dollars more, it is worth it.
