The items that can fill up your iPad quickly are the content.
Some people like to keep their iPads light and either stream or surf the web for content, and some people manage their photos and videos very well, transferring them to their computers regularly and reliably, or use iCloud or Dropbox.
If you keep your iPad lean, you can probably save yourself some cash and get by on 16GB.
Who should move up to 32GB? If the iPad is your primary device, if you play games on it and watch movies and TV shows on it, if you have a decent sized music collection you want to keep with you, and if you shoot an average amount of photos and videos, 32GB is probably your sweet spot.
Some people like to have one device that, while it doesn't do everything all the time, is capable enough to do most things most of the time. As long as there's some extra space to give extra time to managing apps and content, it's a great compromise.
If you store a fair but not overwhelming amount of data on your iPad, you are probably better off going for 32GB. (The editor has a 32GB model.)
Who should go for the 64GB? If you're a power user who wants to keep as much as possible for as long as possible, if you have a large amount of apps and games, TV and movies, and a huge music collection you simply have to have with you all the time, or you shoot photos and video almost non stop and don't want to have to bother transferring it all the time... we'll, you've probably already ordered a 64GB iPad and cursed Apple for not giving you a 128GB option!
Some people really do want their iPad to do everything, all of the time, and never (or rarely) have to worry about running out of space. If you really feel like you need it, you probably didn't need me to tell you so, and you've already decided you're getting 64GB.
What if you choose the wrong size? Remember, in most places you have time to try out your new iPad and return it if you don't like it. Make sure, as soon as possible, you put your new iPad to realistic use. Load up all the apps and games you want with you, load up your movies and TV shows, go out and take some photos and shoot some video. Give it a complete and thorough workout and see.
If it feels like you got too much storage, say 64GB and you haven't even gone past 2GB, or if you got too little, say you're already at 15GB of 16GB, then take your iPad back and exchange it for one that better suits your needs.
If you come to this realisation too late, after the exchange period is over, remember you can buy additional iCloud storage, or look at other options like Dropbox which will let you keep your stuff available online and potentially free up some much needed space on your iPad.
