Indispensable
Though (some) others may not be very pleased, I find it indispensable, and prefer it as my number one online storage.
This not to say that others who are voicing disappointment etc. are not justified, its just that I find it works really well for me, and use it with most of my other apps that require online storage.
By the way, I am using an iPad Air 2 — dont know if that makes a difference, but there you have it.
