It has a display and even bluetooth. The Firmware is open source. The schematics are available.
Imo open source is not that important for an iron unless you want to add a klingon translation. But the iron is pretty good, although it is often rather >50 bucks including shipping.
It’s not that bad. I have a link on my home screen. It is one extra click. I still whish I had a widget or something…
