From your comments I'm assuming it wasn't to do with the usual focusing/weight/cost issues but the actual viewing? Cheers

One thing you have to be aware of with binoviewers is that if the field is wide enough, you will not see either the right or left side of the field with direct vision--peripheral vision, yes, but not direct vision. You can raise and lower both eyes and see the top and bottom of the field at the edge, but rolling the head, even a little, to look at either the right or left edge of the field takes one of your eyes away from the exit pupil.
As a result, many hardcore binoviewer users prefer 40-60° fields, for that reason.
Another issue is substantial light loss and/or chromatic issues somewhere in the field, too. Maybe they're great for planets in a tracking scope, but I am like John B. and never really took to them like many. I always preferred the single eye view.
Now, my dominant eye has image resolution problems, so binoviewers don't even help planets. I can see the appeal, though, given it is often more comfortable to view with both eyes.
