There are rumors they will release a V2 Pro version with touch and backlight in the second half of this year.
They also have already announced the S4 that is basically the same device, a bit ticker with touch and backlight and running android.
Every item you add to the device adds a failure mode. Light is fine. Touch ... I don't know. I like the tactile feel of buttons.
And Android means the device no longer runs on a microcontroller which has consequences for battery life etc. As long as they keep the original, minimal model active with minor QoL improvements, I guess it is fine.
It has perfectly usable buttons. Adding touch feels like straying from the core proposition to have a minimal reader.
