Not got my 6+ yet but have been more concious as to how I do things on my phone.
I usually text with both thumbs so this isn't really an issue.
I used IMDB quite a lot and noticed that I usually do this one handed. This is also that I browse the web one handed. However I have noticed that I do this 2 handed sometimes as well. However not sure if this has been me trying to do this. Browsing news apps is all one handed however I think I will manage this fine on the 5.5.
I watch a lot of TV on my phone, Netflix, Sky Go, Amazon Instant Video etc usually in the evening in bed or when I am travelling for work. I was hoping to ditch the iPad mini for travelling which was a big reason for me going for this model.
I have been having some buyers remorse about my phone as I do have quite small hands but will wait and see what real life usage is like. If it is too big for me to comfortably use I will get the 4.7 6.
I have always wanted the bigger screen but I had some serious reservations about crossing to Android and really thought I would miss IOS. So happy to give the 5.5 a try and really hoping I like it.
