Just picked up the touchbar less version yesterday and am happy I did. In thinking about it, I couldn't see myself using the TB for anything other than annoying my friends with more emojis and feel that's not worth the extra $$.
I'd prefer regular model, the only thing I doubt is just 2 ports on it. It is not a Pro machine with such equipment IMHO. So, the decision should depend on whether it is alright to have 2 ports or it is not enough.
Having used both, including the touch bar-less version, I'm getting the Touch Bar. I'm not sure how much I'll use it, but even if it's a little, along with Touch ID — which I'll use constantly — it's worth it.
as for me. i like the touch bar, yeah it costs us more. it's worth everything from switching function keys to great options for my 3d modeling, photo editing and multimedia projects. it will always up to your need and preference. it's just sad that the regular has only 2 ports. i often use 3 port at the same time.
For me, I think the normal keyboard would be fine for me, I live in a HTML 5 web app and hope to use Dragon Dictation and I can't imagine how different keys would help me. But my wife does a lot of photo editing in Lightroom. I am intrigued to see what the keys and keyboard slider do for her. Right now she can't really edit on a laptop.
