I'm still waiting for the technology to advance. People can't reasonably spend $1500 on the world's shittiest computer monitor, even if it is on sale.
I was thinking, like, a couple hundred dollar Kindle the size of a big iPad I can plug into a laptop for text-editing out and about. Hell, for my purposes I'd love an integrated keyboard.
Basically a second, super-lightweight laptop form-factor I can just plug into my chonky Macbook Pro and set on top of it in high-light environments when all I need to do is edit text.
Honestly not a compelling business case now that I write it out, but I just wanna code under a tree lol
It is nice for some very specific use cases. (They're in the publishing/typesetting business. It's… idk, really depends on your usage patterns.)
Other than that, yeah, the technology just isn't there yet.
