It seems there's a range of opinions on this - no surprise. I find myself frequently, though not exclusively, using my phone (current, iPhone 6+) or tablet for docs while I use my laptop for coding. I know others who do this too. It's all anecdotal, but I don't think of having good mobile support on a docs site as being an edge case.
Also, I work a lot in Django, and love the new site.
