> There is no such thing on the market now
Good news, the ~12-year-old BlackBerry Q20 is back, and shipping, [0] with an updated motherboard. It's a real product, not vaporware; I have two. It has a headphone jack, a small form-factor, removable micro-SD card slot, and a battery that takes little more than a guitar pick and #0 Philips screwdriver to replace.
Parts are cheap as hell as well, with a new screen costing under $25USD, and replacement keyboards under $30.
There's multiple clean sheet designs [1,2] of similar devices as well.
Though I expect them to be treated like fun little runabout cars: made for (typically young) people that can't justify the cost, leaving nobody to buy them, who then bemoan their discontinuation... due to poor sales
