I'm fully aware of that yes, I'm a tech fanatic, I have followed everything apple since the first iphone. I like the look of the iphone 6, the bigger screen is nice but under the hood it's still just running iOS which needs to open up a bit more than just third party keyboards. There are some other features they've added like being able to select a third party editing app whilst viewing photo's using extensions but it's all still very restrictive.
My biggest issue this year is cost, if I had the money I would probably buy it but I have other commitments this year and early next and in the grand scheme of things, a phone isn't that important!
Also, I'm absolutely stunned by the contrast on the AMOLED display, not even the iphone 6 will compare, the new resolution is odd too, so for me I gave a great phone and it cost me almost half the price of an iphone 6.
One last thing, battery! Became tired of charging my 5s twice a day sometimes 3. I've just plugged my s5 in after 1 day 8 hrs off charge with 6 hours on screen time, was down to 5%. Awesome!
