Hello
Fbus02 - I have an iPad Air 2 (Wi-Fi only but w/ 64 GB of storage) - so your first mistake w/ this device is to have purchased one w/ only 16 GB which you will regret (may have been OK 2-3 years ago) - you are quite limited on what to store on this device, e.g. I've added a LOT of MP3 music and apps and have already consumed 30 GB - my main point for your lack of storage is to tell us what your main apps & storage (e.g. music, books, movies, etc.) are desired - you really do not have many choices w/ the 16 GB - sorry but true. Dave
P.S. Depending on your needs, the request for only 'free' apps is also a misconception - again, depending on what you want to do w/ this device, apps that may be to your best advantage may cost a few bucks, so forget about 'free' and pick a price that is acceptable to you, whether one or two dollars or $5 or more.
