Since no one makes Android devices with hardware keyboards anymore, I almost never use this kind of software anymore. After getting burned by a couple of Kickstarter phones hampered by half-baked software and total lack of updates, the only thing I could rationally conclude is that Android as a productivity platform is a lost cause.

When Android was new, I very frequently used Termux and ConnectBot with my first few Motorola Droid phones. For a brief moment, I had a working phone with a great physical design only held back by an outdated chipset and being locked to Planet Computers' abandonware. I could touch-type at 80 WPM on an easily pocketable device! Termux shone there.

So many things about Android were not just more exciting in terms of potential when it was new, but actively better: wider variety of hardware, widely unlocked bootloaders, no remote attestation, etc. Termux sadly feels like a painful reminder of that to me.
