This piece explains the logic behind getting certain relatives a Chromebook so as to relieve you of being tech support: I bought my mom a Chromebook Pixel and everything is so much better now – The Verge.
Now your mom may be tech savvy and not need a Chromebook (my mom was). But for some people’s moms or dads or children, it can be a very good solution. Especially for people who don’t travel much with their computer and who have a stable IT environment (e.g. the networking set up doesn’t change, the printer is good).
Chromebooks may not seem good value. You might compare what you get from a Chromebooks vs a Windows laptop and think: I get more from the Windows laptop. If you are good with computers, that true. But that’s not how to look at it. Factor in the cost of the relative’s computer plus the time you spend solving problems with it. When you factor that in, the benefit of the Chromebook jumps out.
