I did initially but regretted it soon after as quickly ran out of space, despite not having all that may apps on my phone, no offline music/videos etc. At the time I got my 16gb iPhone 6S plus for ?545 and could have got a 64gb for ?600 or a 128gb for ?635 - from a place that sells second hand phones. When they were that price though I kept saying I didnt need more storage - but when I did, the prices had gone up and they didnt have 128gb ones in stock any more and 64gb ones were hard to come by and when I did find one, it was ?660 and came without a box. My partner insisted I got a 64GB from the Apple store instead for ?690 instead of waiting but, ended up spending the extra and getting the 128GB one
. 64GB would have been fine but, if I was being treated I thought i may as well get the extra storage as I wont be able to upgrade again afterwards.
