Bought 3 silicone and one leather case - not particularly liking any of them. The silicone cases feel too bulky and come out in front of the screen too much - when you look at the screen, for me, it creates an odd extra border i don't like, a nasty sort of bumper. I also don't care for it to pop out from the screen because the screens do not get scratched when you lay face down anyway, I should know, i've been using naked iPhones since 2007! So from a feel, look and usability view this front lip is bad in everyway - you lose the best thing about the iPhone 6 design which is the curved edges to run your thumb from when you're swiping from off screen.
I do like the feel of the slicone and the extra grip it provides, plus the fact it covers up the ugly back of the 6 design and those antenna lines. I wish Apple had done a "slim" case though, one that sits closer to the body, flush with the protruding camera on the back and ends on the front stop at the part where the metal ends and the front screen colour starts (and even tapers into it)
Then id love the colours, the feel of the materials and the minimal Apple logo on the back.
Ah well, I guess I can dream about that like I can dream about a super powerful flagship 4" iPhone that has the same specs as the 5.5" phablet plus ha!
