I wasn't being anal, I really didn't know what you meant.
2.35:1 might fairly common in cinemas but 16:9 is way more common on DVD, Bluray and most digital formats like iTunes and Netflix.
16:9 is anamorphic, films are presented in 16:9 but adapted from either 1.85:1 or 2.35:1 (2.39:1 in some cases)
Most films are actually letterbox which is 2.35:1 where even on a widescreen TV you will still get a border top and bottom.
TV shows and some films too are 1.85:1 which fills up most of the 16:9 aspect ratio.

But anyway my point was that if I play a letterboxed movie on both devices, even though the ipad mini has a 4:3 aspect ratio for the screen, it actually delivers a bigger picture than the Nexus 7 which has a 16:9 ratio. And because the ipad mini has smaller bezel in landscape (top & bottom) it doesn't look that much different to the nexus 7.
So to say 4:3 is not as good for movie playback, isn't the whole story. In this instance the benefits of the 16:9 are hindered by the fact the device has a narrower screen, and yet the 4:3 device which has to display larger bars top and bottom actually still manages to display a bigger picture.
So certainly from the point of letterbox (2.35:1 or 2.39:1) ratio, the mini is not as hindered by its 4:3 screen as one would imagine.
A true 1.85:1 (16:9) picture does look bigger on the nexus 7 but again only by the slight amount that ipad mini looks bigger with 2.35:1 letter box stuff.
On the other hand if your watching old TV shows via Netflix or BBC iplayer then the 4:3 picture on the ipad mini wins out as the borders to each horizontal side on the nexus 7 make a 4:3 image seem quite small indeed.

But in general on this topic regarding the mini v nexus 7.
Both are great little tablets, I still don't quite understand why people have to constantly turn everything into piss fight over them to be honest, neither are perfect and either make good tablets. Preference and value is all subjective and personal, it doesn't make your decision right for everyone, only right for you.
I've both, (i bought the nexus 7 with my iPad 3, but i have now side-graded my iPad 3 to a mini because i prefer smaller devices) I am now considering selling the nexus 7 simply because I have a ONE X and both are serving the same or similar purpose right now.
