I had a Nokia E72. Fabulous 'phone that I finally replaced with the iPhone SE (2016), the last iPhone with a headphone jack, (and thus the last one worth buying).
I have an Astro Slide on order, so I shall be returning to a keyboard 'phone, but one that is rather larger:
I had a Singapore version of the E61, which included WiFi (unlike the US versions of the E61 where I live), and cosmetically was all-silver color (no odd-looking gray buttons).
It was such nice physical hardware, one could type messages very rapidly. It was also very durable. (I bounced it off pavement 2-3 times, and literally only got a few scratches.)
I would love a solid trustworthy opensource Linux handheld in pretty much that exact hardware physical keyboard design. I'm primarily interested in WiFi, but (isolated) cellular would also be nice, and maybe LoRa transceiver hardware would come in handy someday.
