Can I get way with a 16gb storage on ipad if I mainly want to use to to paint/sketch, photo edit, and maybe play some games? Or, should I fork out the extra $100 for a 64gb?
Is there a reason why you wouldn't save your sketch/paint projects in an external outlet or via cloud services?
16GB to me isn't worth while for an iPhone, but my iPad is a 16GB model and I've never filled it because I really don't keep anything on it aside from a handful of pictures and the apps I use.
I would never go with anything under 64 at this point. You will have people tell you you can do it but why bother for the extra $100 I would save up to get the storage and make life so much easier.
