My mother needs a new phone. She's found a good deal on an iPhone 4s 8GB. - Is this still a decent phone? - Will it handle a couple of iOS updates? - Should I worry about storage? How much space does the operating system take? She has a very modest phone usage, mostly calls, texts, reading emails, reading a few web pages (mostly news), taking a few pictures, buying bus tickets. No games, no music or videos, no large photo galleries (she has auto upload to dropbox). She currently has a Samsung Galaxy Nexus which I think is now about four or five years old, but it's starting to die. It's got a total of 16 GB storage and her current status on usage is 10,44 GB available out of 13,33 GB. She's the kind of person who uses her gadgets until they no longer work, so she's in it for the long term. Advice appreciated.
