Badluckbro, you are correct, JB (at least the version Samsung cooked for our tablets) leaves much to be desired.
For Youtube, you could go to Settings, Applications, and uninstall the so called Updates. This will revert the app to how it was before.
The stock browser is also terrible. I strongly suggest you download another one. Personally I prefer Boat Browser, as it works really well on this forum (using it right now to type this).
You also might want to Root your device, to gain full control over the notifications window. For some odd reason, Samsung decided to treat our tables as phones, and they don't provide a way to use Tablet mode. Rooting and installing a custom ROM will allow this.
See the All Things Root section for more details on Rooting your device.
