How common is it to upgrade a notebook? What is usually upgraded? I've looked into upgrading my last one, but by the time I felt the need, everything else was so obsolete that it just didn't make sense to put the money into it. This has actually always been the true for me, since my first desktop computer 20 years ago. I stopped buying for the future with my first computer, when I paid a little extra for a second GPU slot for SLI.
