Same here.... external memory (mirco sd card) is a must-have for me.
Since the smartphone inception days, I've been having 4 generations of cellphone photo albums on my phone, transferring from older ones to new ones on a bi-yearly basics by moving the physical memory cards. (Currently about 150GB+)
I think most ppl had changed their usage habit of not using any digital-camera or DSLR these days; it was so crazy convenient to have years of photos on your palm (phone) to share with any family members, anywhere, anytime.
...unless the cloud storage cost is significantly dropped, otherwise, it's still to expensive for yet another monthly payment to our fixed household-income.
