I get the point. And I've been there my self, but after a few years I still dont use it for pictures, excessive amounts of games or music. And taking jojods comments into account then I as him/her self doubt the space will ever get used.
Points.
1. if you're neat, clean and simple user, and not an app- photo/movie hoarder, then space will always be available.
2. No point in keeping apps you dont ever use. - read somewhere that somewhat 70 or 80 percent of apps just lie thereafter 72 hours of use.
3. It's never convenient to stack up 50-100 gigs of picture data etc. If the gadget is dropped, stolen or anything else similar to it. then memories is easily gone byebye.
4. If it's not used for some serious work then it simply serves the same purpose as a phone. and then money spent on something else would all together be wiser.
To sum it all up jojods simply needs to be smart about it or just follow the spender impulse build in to most of us. and the poor thing cant decide. tsk tsk.
BUT if the plan is to eat breathe and live ipad then opt for more space, as mentioned, It's a lot of money to spend to find out that you cannot do everything that you want to on it ending up needing more space.
Simply put. 32 is a little under the belt, 64 is ideal, 128 is too much for average consumers (hoarders dont count. go to bed.

) But to be safe and sound, get the bigger.
If you have had an ipad before and know you wont use it for more than a toilet visit or so, then get the 32.
And dont ask questions like this in here, mixed answers will just confuse you more. there are pleanty of proffessionally considered angles out there.
Your own needs count, not others. Peace
