Look at the Keyphone ($399), Minimal Phone ($399), Zinwa Q25 ($420), Unnecto Snap ($69), and HIT K1 ($349), all via Jose Briones's dumbphone finder.

The other way to go is with an ultra-small laptop (typically 12--13"), a tablet with integrated keyboard, or a (usually DIY) cyberdeck.

If I were going to be nostalgic about a phone, it'd be the Sidekick II (Danger Hiptop outside the US). That was a banger. Physical keyboard, very comfortable form factor for double thumb typing. A modern take on that would be my ideal phone. The first Android Google Dev Phone 1 was also a great device, sharing lineage with the Sidekick.

Waiting for delivery of my Unihertz Titan 2 Elite. Hopefully it’s good overall, but I’m just excited to have a physical keyboard again.

A bonus is that it has some features for interacting with modern interfaces, like touch sensitive scrolling by swiping along the keyboard.

More than the Blackberry... I'd say, the N900 form factor, complete with camera lens lid.
