I get on the forum with my android tablets all the time; both 10" and 7". The new follow along menu at the top makes it a bit more difficult to post or reply to messages when using the on-screen keyboard, but I muddle through.
I have a bluetooth keyboard, but when using the tablets, I prefer to kick back in my chair, so using a separate keyboard is more of a hassle than anything.
I think we can go back to old interface, but I wish we could just turn the floating menu bar off.
