I looked at the Covertec case and it doesn't look like it has a "cover" for the screen. Doesn't that cause the screen to scratch and take damage easier?
With my magnetic mount cover for my I300, it has been dropped a few times and the cover saved me- at least I think so
It looks like the last one you mentioned would be the best since it has a nice looking cover - only problem is it snaps and I could see that being a pain.
Thanks for the links!
