I'm using iPhone 4 with iOS 7.0.3
And it is very slow while typing.
When typing the edit field does not honor the actual screen width so it start scrolling including the smily toolbar.
And after that when doing a line break you end up with a messed up screen where the menu bar starts in the middle of the screen.
See attached pic.
When you are done editing your post you have to search for the actual Post button which scrolled out of view
- many more issues.
Go try it on a mobile device with limited screen dimensions.
