Samsung's ATIV Naming Confusion

Been following the live feed of the Samsung event and the posts surrounding it, but I'm getting confused about the ATIV naming.

From the live-blog:

- ATIV Smart PC:

11.6-inch display, 2GB of RAM, up to 14 hours of battery life. 9.9mm, 750 grams. "Even with the keyboard, it measures just 19.9 millimeters."

- ATIV Smart PC Pro:

Core i5 processor, 4GB of RAM, battery life up to 8 hours. 256GB SSD versus 128GB for the Smart PC.

- ATIV Tab:

8.9mm, 570 grams. (No other info from blog)

From the posts on the website:

ATIV Smart PC's

Differences as above, but the 'regular' one AND the 'pro' both run Windows 8 PRO (not RT).

ATIV Tab

Runs Windows RT

And then they have the Slate 5/7 series as well !? WTF Samsung !?

-------------------------------------

My Point: How are they going to communicate this to the customer?

"Well, you have this ATIV TAB, which can run office but not windows programs. Then you have one step up the ATIV smart PC's which are basically the same, but less battery life but can run ALL windows programs. They are a bit heavier though. And finally there are the Slate 5/7's which are basically the same as the Smart PC's but have a different name (or something).

Can someone please make an overview (I'm looking at you The Verge) of all the differences etc. because even I don't get this anymore. And trust me, It's not that I'm stupid; I can name you every difference between each Galaxy product.. well, most of them, maybe...
