I have the “portable” kind where you can just put it under the toilet seat you have and it connects to your toilet’s water system that brings in water. It was about $30 off Amazon.
It is really straightforward, but my issue was that after I installed it, I had unknowingly unscrewed one of the components in the toilet and it was leaking and I needed some help to figure that out and get it fixed correctly. It was when I was screwing in the new T shaped pipe that it was unscrewing something in the toilet.
There are also the kind that can come built in a toilet, usually on the higher end toilets, or you can get one of the dedicated bowls that is like a secondary toilet seated next to your toilet too.
Most definitely. I used to carry 3 laptops with me, one being Windows, another being my MacBook, and another being a Linux laptop. I now only carry the Linux and Windows laptops and traded the MacBook for a newer iPad Pro. I definitely became accustomed to all 3 OSes keyboard shortcuts.
You do find some overlap which helps. Mac was a bit of a struggle and still is with my iPad’s keyboard in figuring out whether it’s CMD or CTRL key for the shortcut. Even worse was when I used it to remote into a Windows computer as some used one and others used the other as the CTRL key in Windows.
Just takes practice and you grow as you go, the more you use it.
