I use the ProPoint mouse everywhere accept at my desk where I have a docking station that has a mouse already plugged in. For me, it would be easy to see using the ProPoint as my only mouse... of course, I’m confident that once WayTools releases their alternative, that’s all I will want to use.
If MacOS is not a requirement, you may want to consider a Surface Pro. IMO, it, along with a TextBlade and ProPoint makes for a very compact workstation.
When at my desk, I plug into the Microsoft Surface Dock (one nice magnetic connection) and have it drive one 4K external monitor (although it can drive two) and access wired network. Kensington offers a Surface Pro docking station that holds the tablet firmly so that it can be used like a Surface Studio (with, in comparison, a tiny screen).
You can get 16GB RAM, 512GB SSD, i7-8650U (Kaby Lake) for $1700. The dock is available on Amazon for ~130.
Ironically, even though WayTools appears to be an Apple focused shop, I believe the Surface Pro is best suited for taking full advantage of the TextBlade and yet-to-be-named/developed mouse from WayTools.
Of course, if you require MacOS, then none of this is an option.
I’m hoping that if/when Apple moves to ARM cores for their Mac line that they will enable the iPad Pros to run the same MacOS that will run on the Macs. I’ve tried to migrate from my current computing environment to the iPad Pro, but there are too many things I’d be giving up. While there are some things that I find superior on the iPad, the cost/benefit analysis for me still lands firmly on the Surface Pro side for me.
