For me, the following would be the biggest options:
Phone: I use a Pixel 6 with CalyxOS. Since I do video work, having a phone with a really strong camera is super key, and it would be nice to see something where I could pop in a larger lens/sensor for heavy work, then snap back in a simple thing for daily use. Obviously, a super saturated market… but also a market with literally nothing that comes close to this. With all respect to Fairphone, their devices aren’t repairable to the same degree, they aren’t modular, and they don’t compete with my old Moto let alone the latest line of Pixel/Apple phones.
Roku Replacement: Something like the NVIDIA Shield, but modular and based around AMD would be absolutely lovely. Built-in support for apps like Plex/Jellyfin/Emby/Kodi as well as Audiobookshelf (maybe even preinstalled and prepared for full streaming capability). Drop in some software features like an open-source cast function and a Night Listening mode and BAM, you’d have me so sold.
E-Ink device: I use a Supernote and I’m a massive fan of it. It’s got pen-on-paper feel, super strong software development, simple but stylish design… I’m a huge fan. But, even though Ratta is really clear about keeping their devices running for as long as possible, and even though I love their customer service, I’d really prefer a machine that was modular and self-repairable, as well as one with a focus on partnering with open source software.
As a sub-category of e-ink, I would LOVE to see a snappable e-ink screen for the Framework 16 (which I’ll be getting in next year’s batch, yay!). I’m a writer, and I would desperately love to have an all-day battery life screen optimized for writing that I could use anywhere, including in the sun. Then, pop back in the primary screen for teaching work, surfing, and all the other jazz.
Smart/Dumb Home devices: Not as much of a priority for me, personally, but it’d really round out the ecosystem.
