Rich has two desktop computers running XP. Leo says that After April 8, Microsoft will not be supporting them with software security patches, so he shouldn't have them online. Rich can put Linux on them, that would give them a second life.
What should he replace them with? Leo says that a tablet is a good choice for basic needs of email and surfing. The iPad Air is great for that, and it's less expensive, more secure, and easier to use. Leo advises going to the Apple Store and trying one. He could also consider a Google Chromebook.
