Nope, you’re 100% right. Dvorak is efficient because it places high-use keys in the middle row and usually each key alternates between left and right hands. The use-case for a phone is usually single handed, or where you want one thump to be close to all the letters in a word. QWERTY is much better I think for one or two digits.
I tried it for a few hours because I thought it might be faster not flipping from QWERTY to Dvorak depending upon my device.
Turns out my muscle memory when using phones is as good as my muscle memory with keyboards.
In one year I have had exactly zero issues with Linux. In the same time, my brother had OS-breaking bugs happen twice from driver updates with Windows… Once from the GPU, and the other from a CPU firmware update.
You don’t have to switch to Linux. That’s OK. Just realize that you are simultaneously ok with making yourself a harvestable resource that Microsoft and others are milking dry.
