The Pro has a nice backlight that is useful when reading at night. The only downside is the lack of a USB-C port, so you have to use their magnetic dongle to charge. Also, if you want one, I recommend buying from the official site to avoid getting one with the firmware locked (there may be a way to unlock it, but I'm not sure). Lastly, look at the competition: I'm happy with my X4 Pro, but there are a couple of others with different feature sets that are still compatible with Crosspoint and may be of interest if you want to use it for more than just reading.
I'm working on TTZ, a sort of, pardon the expression, next-gen terminal protocol.
I wanted a middle ground between web apps and Terminal UI that allows for things like raster images, vector graphics, simple audio support and file transfer; to let me move more apps and workflows from web apps to a lighter experience.
I have an old laptop that I love and is very nice to use, but since it has only 2 GB of RAM, using multiple web apps is out of the question. I live on the terminal and SSH, but it has its own limitations, like spotty support for images, no audio at all, and ReGis (for vector graphics) support is not available in a lot of terminals.
I've recently finished implementing both client and server libraries for multiple languages (with the help of AI), and right now I'm in the process of fully testing and squashing all bugs and inconsistencies. Next, I will port a couple of applications as a proof of concept.
I plan to publish the source code very soon to receive feedback.
