laptop

Alexis' laptop is on it's last leg. It's running really really slow, like molasses.
It takes forever to boot up and load all the applications. I wonder if it's because of all the junk that's been downloaded in it? I want to clean it up and delete unnecessary files, but I'm afraid of deleting something I'm not supposed to delete. My thinking is, since laptops are now disposable, I can just let this one die a natural death and then replace it with a Sony VAIO. I've heard a lot of good reviews about the Vaio, I'm sure I'll like it.
