Dave has been holding out for Windows 10 because he thought Windows 8 was terrible and didn't upgrade to it. Leo says that Dave's instinct was spot on. But Windows 10 is lightyears ahead, and in fact, you could call it Microsoft's apology for Windows 8. Windows 10 is very similar to Windows 7 in feel. However, the world has changed, and a general purpose device is no longer the way we compute. They're a security issue as well as being overly complicated and unreliable. This is why tablets and smartphones have taken off. So why not rethink it and get something less complex like a tablet or even a Chromebook? It's very secure and reliable. Great for general computing, word processing, and internet surfing. And if something goes wrong, Dave could use the powerwash feature to get back to factory defaults. He should avoid the real cheap ones and get one from Dell or Asus. Leo recommends getting it with 4GB of RAM.
