They came out with one this year, type on it and get back to me and tell me how awesome it is with no spacing between the keys and a 4 inch screen, this swiftkey love is mostly due to bigger screens swiftkey lacks proper spacing I know I hatred my droid phones with swiftkey installed and I type better on this small ass iphone 5.
Ah, you're talking strictly about screen size.
Yes, for sure, a smaller space will make it more cramp to type. But you're implying Swiftkey is only so good because it's on a big screen. That helps, for sure, but it's good and better than iOS' keyboard because it's simply good and better than iOS' keyboard.
