I have an old laptop (~4-5 yo) running Vista that had been my daughter's. It was running very slow, taking a long time to load web pages and such. I ran virus and spyware checks, removed a lot of programs, and cleaned up the startup programs, but still didn't run well. For $15 I bit the bullet and did the upgrade, there is a learning curve, but the system browses the web fine now, which is about all I plan to do with it.
