@thibaultamartin @purism @KekunPlazas The NexDock Touch is the only option I'm aware of that's currently available where I am (US). It's not perfect (the touchpad on both it and the NexDock 2 is notoriously awful and pretends to be a mouse instead of actually presenting itself to the OS as a touchpad) but so far it's all we've got.
In South Korea there's the KT Flipbook, but I haven't found a way to buy it from here.
First company to make one with a decent touchpad gets my money instantly.
