I've got it.
I went for the 10.1v instead of the 10.1.
The Vodafone sales people told me, the "v" stands for Vodafone...
I've got no idea, whether that's true (other providers such as "Base" offer it as well, though).
But from what I understand:
10.1v is the "original" version, Samsung did present about 5 months ago.
After seeing iPad2's specs, Samsung decided to streamline their flagship tablet.
They've reduced the quality of the back-camera, reduced the weight by some 20 grams (now being slightly less heavy than iPad2) and reduced the depth by some 2 millimeters.
I don't care about the "better" camera in the 10.1v.
I don't mind the 2 millimeters and the 20 grams more. It still is extremely comfortable to hold and feels way less bulky than Motorola Xoom (my favorite Honeycomb tablet until now).
But I've read (didn't check in person, simply didn't want to wait another 10 days or so) Samsung 10.1 (without "v", the streamlined one) would feel kind of "flimsy".
My train of thought:
10.1v already had been approved.
Samsung certainly is experienced enough to know what they're doing.
I don't mind the few grams more, but I'm a bit sceptical about the "quickshot" to get rid of some weight and depth.
I'll check out the Samsung 8.9, for which there's only one version (no "v"), just the "streamlined" one.
I'll give my usual comments about Samsung Galaxy Tab 10.1v in a few hours and over the weekend. Especially in comparison to my other Honeycomb tablets: Motorola Xoom, Asus Eee Pad Transformer and Acer Iconia.
For now: Very nice.

The setup did allow for various languages and countries, which wasn't available on Xoom or Iconia...
