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.
