I work for a company which has developed a special purpose drawing (well, entry-level CAD) app, and for a long while, it didn't have keyboard shortcuts, and that was probably because I mostly used it on my Toshiba Encore 2 Write 10/Samsung Galaxy Book 12/Samsung Galaxy Book 3 Pro 360, so would use it w/ touch and stylus, which was quick/natural enough that I never felt the need for keyboard shortcuts.

Such usages pretty much want a very flexible device though --- I'll often use mine fully flat on a lap desk and will rotate it in various ways depending on what I'm doing, and will then further mix in using my Kindle Scribe and Samsung Galaxy Note 10+ (which use the same stylus tech as the GB12/GB3Pro360).

Sometimes I'll add my MacBook into the mix by way of a Wacom One display, but I have a 1st gen unit, so no touch, so every so often I'll find myself dragging at it to scroll or tapping a control with my left hand to no effect.

I'd like to try Apple Sidecar on an iPad (which arguably is Apple's touch interface), but can't justify the expense, esp. for yet another stylus (I couldn't easily count how many I own, and carry a spare Lamy Wacom EMR in my sling bag), esp. a stylus which only works on one device.

Still waiting on Apple to make a replacement for the Newton --- the smallest size iPad which supports the Apple Pencil is close, but I need something daylight viewable, hence the Kindle Scribe (which I'm going to be replacing w/ the KS Colorsoft presently).
