I have nanotexture on my macbook pro but do not on my ipad.
A couple of reasons:
To get nano on the ipad, i’d need to go for a 1TB/2TB model, and that’s a big step up from 256 which is already more than i need.
To get nano on the macbook pro was a 150 AUD option on a 6,800 dollar laptop, so it was a no brainer.
On the macbook pro - i don’t think i’d ever go back to glossy.
On the ipad pro - i think the device is small enough and generally frequently hand-held enough that its not too inconvenient to just… tilt the thing differently to not be reflecting the light in your face.
YMMV - if nano was a $100 option on the ipad for any capacity i’d get it.
But i’m just NOT going to go up several tiers in capacity at significant cost before having the option of nano on an ipad.
