Meh. It'll happen, or it won't. The market's volatile and fickle.

It doesn't mean will it happen or not, Thunderbolt 3 is great thing for now.

It's a neat, but very niche, piece of technology. It's not dominant, in any sense of the word. It might be in the future, but it's not a sure thing. The fact that you can find hardware that supports it isn't interesting to me. It'll be interesting when I can be just as sure that a machine will have a TB3 port as I can currently be that it'll have a USB-A port.

One of the things I actually dislike about it: a port can be USB-C without being TB3. That's going to be fun with the plain USB-C port in my laptop.

It's not a niche anymore, Intel 7th gen has native Thunderbolt 3, so no extra chips needed, that should expand its popularity. Actually any modern laptop already comes with a TB3 ports (see Dell/HP/Apple stuff).

It doesn't need to be dominant as in "every PC has it" and everyone needs it. Most people, all they need is an iPad.

It is dominant in the market where USB falls short, that's what matters.

Everyone doesn't "need" it. It'll just be nice. As you point out, most people don't "need" anything more than a tablet, and those aren't exactly known for their high levels of connectivity.

It isn't dominant in the market yet, and that's my entire point. When it is: cool. I don't have much argument against it (aside from the dongle-hell I'll be living in). But right now, I don't own a device with any version of Thunderbolt, even with several new laptops around.
