You know, anyone who read your post realizes that your weren’t talking about your PC or your OS. You were really talking about your need for a standard sized keyboard.
Standard size keyboard and laptop. Neither of which a tablet provides, and I can pick both up along with plenty of other things for about half the cost these days.
If it wasn’t for the occasional need for mobility - I could run just fine on an old tower these days now that I have a car. Same as I was 15 years ago. I’ve thought about going back to that - since you can build a decent rig for cheap, but I’ve gotten used to a laptop and it’s quirks. :)
Tablet? What on earth for? It does nothing that the laptop doesn’t already do.
