This looks useful for people with poor eye sight, want a bigger screen or find holding a tablet easier than some smartphones which are slippery to hold because phones are very thin and have glass backs like the Samsung Galaxy S7 with a glass back.
I wonder if this tablet would work on tablets as well to create a dual-display tablet like dual-display desktop computers, or let kids use this cheaper Superscreen tablet instead of using an expensive tablet like the iPad Pro, Samsung Galaxy Tab S3, Microsoft Surface Pro, etc which can cost $1000 when you buy the most expensive model with a lot of storage.
