Yeah I was gonna say that while it sounds completely unusable, it's surprisingly not too bad actually. Some of the more complex shortcuts can get pretty tedious, but nothing that a good config can't solve.
I remember once my friend's laptop died, and while it was in RMA he was using his phone with an external keyboard and mouse to develop a webapp lol. Just goes to show that any computing device that can run a web browser and VIM covers 90% of your daily software needs haha.
What keyboard do you use? Do you need something like Unexpected Keyboard, or are you still able to be productive in vim with a more "standard" Android keyboard?
Personally I just run gotop at startup and keep it on my second monitor. I know it's a small waste of resources but I enjoy watching the blinkenlights.
