All wrong, but you have to read ! You can choose it ! The nanotextured glass is only available for the 1000 and 2000 GB versions.
It is only recommended if there is a lot of light at the workplace or if you are working outside. The contrast and saturation suffers compared to the standard glass.

Wrong again. Yes, it did.

First answer was wrong. Sorry. I meant from 1000 GB memory.

No. Only from the version with 500 GB storage
