Don't bother with the toucbar, i have not had any need for it, and j do a lot of Photoshop and a fair bit of video editing, wish I had saved a few quids. Maybe in a year or so the touchbar will be more useful but not now and probably not for what you need anyway.
I don't know tbh - what does the touchbar bring to the party, or rather what do you lose without it?
I'd kind of assumed that I would get one with it as I presume that's the new standard.
