It sounds like you could possibly be new to Frontier and wondering if the 16 you currently own would be adequate, or if you should spend the money to invest in one with more memory?

If this is the case, congratulations!! And welcome to Frontier!

If you currently own a 16 and are wondering if it would be adequate, the answer is absolutely 'Yes'. (It is rumored that first year pay at Frontier could be subpar? Save a bit of money if you already own a 16G iPad, and pocket the stipend).

If you are in the buying mode, absolutely get one with more memory! I'd say, get as much as is available, and grow into it in the next few years.
