As simplistic as it may sound, the consensus among the tech community is that thick bezels are bad, and that thinner bezels are generally good. From an aesthetic point of view, it's hard to counter this judgement, and per the W4pHub report, the bezel of the Surface Pro 4 will be so thin that only the bottom bezel will be especially noticeable.
The image posted above is the one shared by the source of this story. Disregarding the fact that it's an ultrabook, though, we could be looking at a form factor similarish to the Dell XPS 13:
The report also claims that the Surface Pro 4 may include a special 'Smart Frame' feature, which will alter dependent on whether Windows 10 is in desktop or tablet mode. In a nutshell, this would mean that in desktop mode, you'd get something like the top half of the Dell you see above, whereas in tablet mode, the frame / bezel area would broaden, making it easier to hold.
Whether there's any truth in either of these rumors remains to be seen. But with October 6th now market in the calendar, we shan't have to wait too long to find out.
