I bought the iPhone 6 Plus 64Gb on release day (Pre-ordered, didn't queue!). After using an iPhone 4 for 3 years now and getting madly frustrated with it's sluggishness, I have to say I love the 6 Plus! The size might be too big for most people, but I love it. The other day someone asked me to look at their 4S and I couldn't imagine how I lived with using such a tiny screen!
I am annoyed with how long some of the major app companies are taking to update their apps for the iPhone 6/6 Plus. Some examples are WhatsApp and Facebook, both of which look rather dreadful on the iPhone 6 Plus with huge text!
