I am planning to buy an android tablet for my mother (not a tech savvy person at all) , any suggestions for 10" tablets. What are the things we look for when buying a tablet. She will need to read some newspapers, have GPS on it, play sudoku and other puzzles, listen to radio and songs. Further, is there any simple app, where she can enter phone numbers and addresses from her address book. She is old fashioned, I want her to copy all her entries in her address book to this app so that it is easy to search when she needs it. Her addres book is very unorganised, it is not in any alphabetical or any order.
