My worry is about my lifetime license eventually turning into a subscription requirement.
I love the self awareness.
I'm trying to be better about factoring in my time, largely unsuccessfully.
E.g. I just spent $200 of my time trying to trade in an iphone at the apple store (the Apple Store sucks now and has terrible processes). Value of trade in: $200

edit: Ever since I read the Timeframe article I've been itching to do the same thing myself, but I suck at these things so worry that I'm just going to end up with more piles of electronic parts in my cupboard of broken dreams.

I cannot find a mention of the developer edition. I own a TRMNL and use the api for free (I assume because I have a device) and then they offer a lifetime $50 license to use their backend with your own device. I think that's fair.
Also, I don't quite understand their back ordering information. I ordered mine and got it less than a week later even though they said it was back ordered.
Or at least I've developed HTML-based views that are custom (I think that's "plugins") that are displaying on my device.
You can do it! :-) Also happy to help if you have questions.
I'm currently making something inspired by your Timeframe, but using an OLED panel, as a 2nd screen for my desk - but almost the same form-factor and a similar design.
I'm trying out a faux 3D-printed wood process with wood powder-infused PLA, sanding and staining, and a faux wood grain I baked into the geometry using a displacement map, though. Hoping to make it all posh.
Your time does have value, but it’s in terms of opportunity cost, not hourly wage. Presumably you wouldn’t have made $200 had you not gone to the Apple Store (unless you went when you were supposed to be working and have a job where that time becomes unpaid).
Although in hindsight it probably felt like I spent more time there than I actually did. I think the $200 is fair given that I would normally be quite willing to pay to avoid that kind of unfortunate circumstance.
And of course that leaves out the complication of pre- vs post-tax wages, retirement savings, etc.
This is also why I buy almost everything from Amazon. Their returns process is worlds ahead of every one else. It also doesn't hurt that drop-offs are at grocery stores.
Apple made me call to cancel the trade in, then said they could do it in store. They could not, not then, not an hour later, not days later.
Internet and apple store employees said it should be fine. I guess they don't make geniuses like they used to.

Is the API is basically "Push PNG to server, PNG displays on whiteboard?"

You write HTML templates (that are stored on their servers) then can post data to them (or have them poll an endpoint to get the data) to "merge" into the template.
Think:
And you need to provide (via push or pull): That might not be the exact syntax (I wrote my custom plugin a month or two ago and haven't touched it since).They provide a "UI Library" (Design System) [0] to give you building blocks of UI to use if you want.
It made it really easy to get started. They limit to 1 screen update every 15min (that is the fastest you can have the screen update). But you can press the restart button on the back of the device to force it to update, you might need to force your plugin to re-generate the image before you do that.
If you want to flash your own firmware you can lower that (at the expense of battery life) value or even have it call out to your own server that can do whatever you want.
