Where? All I see is a bunch of people saying "If you're going to spend £300+ on a PC that has to be used with a dock that's about the size of an NUC, you may as well 'just get an NUC or similar' (quoted DIRECTLY from CK_1985) for less money". Nobody made this an Intel/AMD fight until you showed up. The NUC has been mentioned because it's probably at the forefront of the tiny PC revolution right now, readily available, in a comparable size, for comparable use, and it's much faster to type than "A. N. Other small form factor PC". We could talk about the Gigabyte BRIX, but not many people would know what we're talking about.
The Tango requires the dock to function - you can't just whip it out of your pocket and hook it up to the nearest monitor. Either you're carrying the dock with you, which defeats the point of the "tiny" PC, or you're spending a small fortune to have docks put everywhere you're likely to use this. If this wasn't the case, and the PC could function in its entirety without the dock, I'd say "Great, this sounds cool, I'd dig it". As it stands, you've got to plug the tiny Tango in to a much larger system. Which defeats the point - either spend £65 a pop on docks, or carry the thing round in a bag.... at which point, enter the NUC!
I can carry round a CPU, SSD and 2 sticks of RAM in some anti-static in my pocket perfectly easily - doesn't mean it's a PC.
