Kevin is trying to make a really old Sony Vaio laptop with Windows XP usable for his mom, and is wondering what he could do with it. Leo says why not put Linux on it? He likes Puppy Linux or Darn Small Linux. It works great on older hardware and will serve to protect it while it's online.
However, Leo says that since he's going to work it out for his mother, a tablet is a better option for her. The iPad or Google Nexus 7 are both great options. They would be way more powerful that that old laptop. Even a smartphone would.
