God I miss real keyboards like this.
I make due with a Unihertz Titan Slim. Not the best, but with custom ROMs, a temporary relief. I will buy another one or two but after that, I have no idea what next. Hopefully, someone else with make limited edition niche devices.
The problem is that the physical keyboard takes permanent real estate whereas the software keyboard can come and go, to allow for full screen applications.
I do miss innovative phones like the sidekick, LG chocolate, and other slider ones.
