The detachable cable would be great. That’s the one thing I worry about with mine. The fact it is USB C yields little value right now. USB C ports are more limited than A if you have multiple peripherals as very few items chain and the same for hubs. Yes you can switch C to A with a single cable, but they are more expensive and all USB C cables appear to have more significant length constraints.
The stand doesn’t look like it is as adjustable as the old one, so that’s a negative. But, I guess you could create your own adjustable stand.
The face plates don’t interest me, but I’m sure you could get a decal created and put on a 3D printed face plate for the v1 if that was something you wanted.
The new software has been out for a while and works perfectly well with the v1 deck.
Overall I see no driver to upgrade. This is a release just to freshen the product line, not advance it.
