What are you wanting to backup, photos backup to drop box and apps live in the cloud outside of storage space?
I have the 16gb phone and the phone tries to keep itself backed up iCloud, given the free space is 5gb (?) obviously it fails. I would like it backed up so if I need to I can restore (like android does, automatically, for free), and it came in useful when I woke up one day to find my first iphone dead and needing replacement.
Not sure why you need a physical back button? Button is on the top left of pretty much all apps?
I hadn't realised the joys of a physical back button until I was without one. Say you click the wrong link in an email, or click it by accident, IOS loads the browser and the page. On android you instantly hit back and you're back at your email, on IOS you wait for the browser to load, the software back button is of no use here, so you double click the home button and swipe the browser up to close it, then select the email app again. People tell me that this isnt a big deal but I disagree.
Agree with notification issue, although doesn't happen very often, what's app issue is due to non proper multitasking, also a slight annoyance, but more so for other issues than waiting for a second or so for what's app.
I think my case is more acute than others because my commute is very patchy in terms of reception, I almost always get a notification on my phone (showing me the first 3 of 4 words of a message) but because of lack of signal I'm unable to see the rest of the message. I have to sit waiting, with the app open, hoping to get some signal so it will pull in the message. For me this is the biggest issue with the phone. On the occasions when I get the first few words of an important message I have been close to rage waiting for the rest of the message.
Android is far from perfect, and it's probably the case that because I grew up with it I overlook its flaws.
I don't have a problem with the price of apple, their hardware and build process is good (Ive been unlucky with dead phones). Also if I used their architecture elsewhere I'd put up with the issues to have all my devices auto-sync. I also bought my mum and grandparents iPads as their first tablets because I knew the learning curve would be easier.
