answer:It depends on the amount of data and app you want to download. I’ve personally found that the largest uses of storage are the documents and files, not the apps. By combining all of videos that you take with your device, it can add up to several gigabytes of data. Audio files and songs take up a lot of space. If you plan on using the device as a permanent storage location for larges amounts of videos, presentations, audio files, and the like, then you should get a device with a large amount of storage. If you plan on deleting / transferring any data off the device that you don’t actually need on the device, then 16G is enough (that’s what I’m using right now).
