Yeah, including the part about biting like *************

Where are we supposed to report problems? Here are mine:

It froze my machine.

Specifically: the desktop now displays (from top to bottom)

A LARGE DIGITAL CLOCK (with a slightly incorrect time)
The date
A battery indicator

(My previous wallpaper, at the wrong size; it's far too big. It's a text block that says "PLEASE DON'T TOUCH THE SCREEN," but the words now flop over both edges)

A "lock screen" icon on the left, facing a "volume" icon on the right.

There are no apps or anything else at all on the screen.
Nothing works. If you push the lock screen or volume icon, the one facing it slides over, but they don't do anything.

None of the buttons (the physical buttons on the bezel) work except for holding down the rotate one for a long time so you can shut the machine, plus the arrow button to back out of that.

I seriously don't recommend anyone installing the beta at the current stage.
