Ubuntu:

I'm still using Ubuntu Mate 16.04. But you know that they come out with updated versions of the different operating systems each year in April. So, I'm contemplating trying out different OSes again. Every few years I do that. I was using normal Ubuntu since like 2007.

Unity

But switched to Mate around like 2016 after I got tired of the Unity UI. Oh, years ago, I think my brother had that Commodore keyboard video game computer console thing as seen in your photo above or something that looked almost identical to it, assuming there were different ones that looked similar to that. That picture says Commadore VIC. I will have to Google that to see.

Tablets

Is Ubuntu not working very well on tablets? That is too bad then. I'm no expert, but I should buy a tablet someday and experiment in order to figure out what might work best on a tablet. I just use my laptop, generally, so I wouldn't know.

React

When you say React, are you talking about an OS? If so, then it sounds like it has a limitation then.

Web Designer

I have done web design and I know how to Google to find code, but I don't know a lot of code personally like you do. I am more a writer than a coder. I mean, I just like to write. But some years ago, I was working with a friend on a Facebook competitor website called Mea Omnia. After like a year, we kind of gave up on that project. But that was before I knew about Steemit which is somewhat similar to what we were trying to build. So, I have experience in building websites. I know that it is a lot of work.
