Mac OS X is the modern Unix that is easy for the average computer user. Linux isn't there, except for mobile devices running Android. And some special purpose devices like home routers and Tivo.
The same place she goes now... Me, and others like me.
That isn't going to happen. Grandpa needs a trustworthy vendor to get help from.
I don't think you realize how deep the Linux revolution goes
I have been running Linux for 14 years. And for 14 years I have been hearing the same thing about Linux going mainstream on the desktop. It isn't going to happen.
I literally don't know a single service tech who is not at least passingly familiar with Linux, and most that I know use it regularly.
That has been true as long as I have run Linux. Most of these techs went to colleges that ran Unix. Linux is an easy step and cheap step for them. So what? I have been around techs long enough to know that the vast majority can only explain things to other techs. They have no patience or communication skills for explaining to Grandma how to fix her Linux box. In fact they will think she is an idiot because she can't figure it out on her own.
And about 1/3 of my Linux desktop users ARE Grandmas, btw.
And how many millions of Grandmas are you supporting? And how much does the job pay?
LOL! yeah, right. Whatever. take em to the EEk Squad ROTFLMAO!
