Example Input: Fun to use & very functional. User Guide & tutorials inadequate for me who is computer challenged. Love reading on it! Like that I can adjust print size so I read with my bifocals then change for my contacts. I don't have to pull out reading glasses. Excellent buy!
Example Output: Fun reading!

Example Input: My PC loads so much faster. Very good product.
Example Output:
Very good product.
