Ok, I've been using ios 7.1 for a while now. And it's definitely better. However one very odd issue has been the screen corruption when you press a key on the apple keyboard. AFAIK, it occurs only on the white keyboard, and it's not reproducible and seems to happen randomly. The instance when you press a key, a rectangle that surrounds the key is filled with horizontal stripes of colored random noise. Continues to happen after reboots. Hard to notice.
