I got Minecraft PE and I LOVED IT!!! I saw a lapis lazuli block. I thought it was a squid spawner. And I placed it on sand. I was thinking "Why won't it work?" So then I thought, "OH WAIT!! I DIDN'T PLACE IT IN WATER!!" That didn't work. So I figured that squids weren't in Minecraft PE yet. So I built a golden house, Nyan Cat, a roller coaster, a library, and a life sized grass block. So that's my experience. Hope you enjoyed!
