Is everything new from Samsung some sort of Galaxy?
At least their top models. Apparently they listened to what people were saying about all the different phone names being confusing.
This looks quite good, but now I wonder why the carry two 10" tablets, just because this one has the "special" stylus?
Who would carry two tablets?
And also, pardon the ignorance (haven't been up to speed on Android tech as of lately) but isn't this kind of multitasking not available on every Android device?
For now, but I think we're going to see a lot more multitasking like this in the near future. Wind River has announced code for OEMs and others to customize Android with multiple resizable windows, for example. This can make sense on tablets.
If it becomes popular, I think multi-window capability will appear in the core code. (It's already half there. Widgets are simply windows that appear in another app's screen. Part of the original slowness of Android windows was because this core cross-app capability was cooked in from the beginning.)
If so, this means the Android version carried by this device will be a "special cooked ROM by Samsung, not available on any other Samsung device"?
Yep. Some people are always talking about how Samsung should "stop copying others" and differentiate themselves. Their wish is granted. Nothing wrong with a specialized device having special capabilities.
HTC has the same thing with their pen based tablets.
It'd be better if Android itself had a standard API for active pens.

The galaxy s3 has the pop out play video option, but not the side by side apps.
There's also the third party Overskreen browser. It allows multiple copies of any size on a homescreen at a time.
