You've potentially got multiple definitions of tablet in your post. The modern "tablet" like an iPad, Surface, etc, and the graphics tablet. Perhaps Wacom now offers a modern tablet, but they've always been a graphics tablet company.

Wacom are the leaders in graphics tablets. These replace the mouse with a pad+pen combo. Artists love the control they get (high precision pressure sensitivity, tilt angle detection, twist angle detection, all at high data rates... basically it will capture most of what you can do with a pen, pencil, paintbrush, etc.) Every artist I know loves them. They take a while to get used to though, and you need to be doing something artist-y in your post processing for it to make sense, where you'd prefer brush strokes over mouse movements. I have a low-end one (Pen & touch, it detects pressure, but not tilt, rotation, etc.) and never use it.

They made versions of their tablet which had integrated monitors, so you could see what you're drawing on. These still needed a PC, and just worked as a monitor/mouse combo. They were a good idea ruined by a low-quality monitor with low contrast and a cheap TN panel. At Corel they had an enormous more advanced version that was like a monitor that works like a drafting table. I'm not sure what the monitor quality was like on that.

So, while it's possible that Wacom now offers what people think of as a tablet, that's both a graphics tablet and a modern tablet (likely either Windows or Android, not iPad), I would heavily research the computer part, and the display. They know what they're doing with pens, but they've shown they don't know how to make a premium artist quality display in the past. As full PCs are not their specialty, I would imagine such a tablet would be something low-end, re-branded. I'd more look for a premium tablet that say it has Wacom technology (Surface Pros were supposed to get this, but I have no idea if that deal went anywhere), as opposed to a Wacom branded tablet.

I'm not sure how the Apple pencil on the iPad Pros compares to Wacom's pens. I know it can detect pressure and tilt, but as I don't work in an artistic industry anymore, I haven't heard any artist comments on it.
