Sure, you could keep using Windows, although Windows 8 looks worse every time you look at it; or you could buy a Mac for big bucks; or you could buy a Samsung Series 5 550 Chromebook starting at $449 and have a great Linux-based desktop that you already know how to use.
What’s that? It’s Linux and that’s so complicated. Oh please. Get into the 21st century, Linux is easy enough for grandpa and grandma to use. And, besides if you know how to use the Chrome Web browser–you do know how to use a Web browser right?–then you already know how to use Chrome OS and a Chromebook. If you really want to have the full Linux shell command experience, you can have that too, but it’s purely optional.
