i doubt if anyone here ever experienced the limitation of "cloud storage", especially if you're away from the States and out of the country with no LTE nor WiFi. It's too hard to share all those memorable videos to friends and families while visiting them overseas, but without any international data-plan or free wifi.
Eg. in rural area of Europe, free wifi was not easy to get.
...so, to avoid further limitation, i would think "external memory" being a must-have for ppl like me.
