All works, including weave sync.

I like the keyboard shortcut. Unfortunely, that means one has to open the keyboard and landscape. The keyboard shortcuts are cool

Smooth and relatively fast.

Some mild bugs, like virtual keyboard does not go away till your open/close the hardware keyboard.

Pros:
lots of plugins
weave sync

cons:?
