I am new to the android development game and I am planning to get my first tablet soon. I know that most android devices in use are phones. I am planning to get a 7" or a 10". I want my apps, which will include both utilities and games, to work well and be entertaining on phones and phone-size tablets as well as large tablets. Should I buy a phone-size tablet instead of a 7 or 10" tablet to ensure that my apps work well for that size, or do you think I'd be okay developing on larger tablets?
