Can confirm that you do not need the dock to enter show mode.
Can confirm that you can not get to AT while in show mode. If you have AT loaded in regular tablet mode, you can say, “Alexa, Exit Show Mode” and then AT will pop up. To enter back into Show Mode, you can say "Alexa, Lauch Show Mode.
Can confirm that Blink camera still doesn’t show on the Fire Tablets even in show mode.
Can confirm that you can drop in on a device but a device can not drop in on the tablet.
Can confirm that in Show Mode, the announcements from Echo devices goes to the tablet. (not true if not in Show Mode)
Switching between show mode and regular mode is a simple swipe down and clicking show mode on/off. Update: Can also say, "Alexa, Luanch Show Mode or Alexa, “Exit Show Mode”. This is useful for Action Tiles
All in all, the Tablets in Show Mode, act just like the Echo Show which is pretty cool.
Tablets mics are no where near as good as the Echo devices. With an Echo device, you can typically say Alexa and what you want in one smooth sentence. With the Tablets, you have to wait for the blue light then go. At least in my experience.
You can not drop in on the Tablet. This feature would have allowed for the un-pairing of Tablet/Dot in each of my rooms. I love the drop in feature and the announce feature!
Show supports more cameras like the Blink cameras.
No manual way to invoke Alexa while in Show Mode.
Not locked in to just what the Echo Show has to offer but also have a full out right tablet!
You now have a Show features on a 10" screen so the visual feedback is much better. Especially videos.
You now have an Aux cable that you can use.
Echo Show now becomes portable.
