As you decide exactly what to ask Santa for, there are other things to consider.

Size: I started with a 10”. It didn’t fit into my upright's case pocket. The tablet plus a music stand felt like carrying a around surfboard. For me, the best compromise between readability and portability was an iPad mini. I found the 7-8” size slipped into my jacket pocket.

Security: music stands are tippy, tablets are fragile and aren’t cheap. Figure out a way to easily attach (and remove) your tablet to/from your stand. Even a little self-adhesive Velcro on your tablet's case (yes, you want a case too) and the music stand can save a lot of hassle when your stand get's accidentally jostled.

Back-up: I always try to remember to load my gig-lists into my Phone in case the magic-smoke escapes from my tablet.
Note, I recently replaced my “old” phone with a 5.5” one. While I prefer using my tablet, I could definitely play a gig with my phone positioned on the shoulder of my low-side upper bout.
I put some Velcro on a shoelace which I can wrap around the neck under the fingerboard of anybody’s bass and attach the silicone phone case in just the right spot.
A guitarist I’ve jammed with has an elastic strap he Velcro’s around his lower thigh which securely holds his phone... it works for him sitting in the jam circle.

Power: be prepared for a dead/low battery. A good power-bank will hold a charge for months and takes little space in your case. At gigs, reduce the brightness to only what's required. I think using “night mode” (white text on black) may help too.
Night mode is activated on the font-selection screen (Aa). I prefer it except in bright sunlight.

Let us know what you get and how it works for you.
