I had the original Mini and iPad 4. The Mini was used 99.99% of the time. I bought an rMini early last week, and used it much more than my Air, both for web browsing and movies. The Air is more immersive as a video player, but the rMini will do the trick. I returned mine because the lower portion of the screen around the home button was yellow, and Walmart charged me $629 for the 64GB wifi version. It was the only one in town at the time, but now there are plenty. I'll probably buy another.....Does someone have air and the Rmini at home?which one do you like more?
I'm sure you must be referencing some viewing distance calcs, but for real world impact, I would need to hold my ipad Air less than a foot from my nose to approximate the coverage I get from my 73" at THX recommended viewing distance.An iPad Air held at 16" will be the same size as a mini held at about 13". This is also equivalent to watching a 70" TV from a little over 9 ft away (i.e. across a small-ish room).
You can probably change the picture size on your tv. On mine which is not particularly new, I can switch to 4/3, 16/10 or zoom 1/ zoom 2. It appears that zoom 1 setting makes my airplay video filling totally my 16/9 screen. Hope this helps.I like using the mini to watch movies, only thing is when I decide to airplay to my apple tv; it would be nice if the ipad would switch to a 16:9 mode so the airplay mirroring would fill the entire HD TV screen
