There are many sites and online forums which extoll the virtues of choosing either the iPad Air or Retina Mini now that the mini is in the wild. I would like to start out by saying, you really can't go wrong unless you get the 16 GB version of either model, I do recommend the 32 GB or above on either model. I picked up the 64 GB as it seems to hold what I need it to without an excess of wasted space. Screen Size Matters The iPad Air has the same 9.7 inch screen as all of its predecessors though the bezel has been reduced greatly. With the larger screen it's easy to watch movies, surf the net, be productive, and not be limited in any way. It is a larger screen and full retina which means at normal viewing distances, the human eye can't distinguish the individual pixels. The screen is beautiful and even though my last iPad (the New iPad) weighed in at a hefty 1.5 pounds the flexibility offered by the larger screen has kept me coming back to the larger size and not ditching it for mini. The iPad retina mini has a 7.9 inch screen and is palm-able, the screen is super clear and retina just like its big brother. However, when at the Apple Store last night contemplating a return and exchange, I found that I did prefer the bigger screen. It's just better, well, for everything. Movies seem to render better, there is more room to type, I do have big fingers, and the larger screen is better for photos and movie watching and said surfing. Though many reviewers point to the portability of the iPad Mini Retina, it isn't as if the iPad Air isn't portable it's just the iPad Mini Retina is more portable. One other comment on size, my other computer is a first gen 15" Macbook Retina and I have an iPhone, for me the Air seems to occupy that space between my laptop and iPhone better. To LTE or Not to LTE I wrangled with this question when I bought my 3rd Generation iPad. I splurged and bought the 4G LTE model and I had 4G available in most places. I almost never used it. I did bring it to work occasionally and it was convenient to just be able to use it at work (no wifi) but not worth the extra $130.00 plus $10.00 per month to add it to my cell plan. I am on a family share plan with my carrier which means I get free tethering. Free tethering means that if I need data I can tether to my phone to get it. My iPhone is a wonderful enough GPS and I don't need the big screen in the car. I simply thought my money was better spent on AppleCare or a nice Smart Cover. Plus when I got my price on my previous iPad, on one of the popular buy back services the difference in the but back price was zilch between the two. If you are a road warrior and need your iPad while traveling, then maybe if go for it, otherwise save yourself some dough and stick to the Wifi version. I know this is lengthy but I wanted to offer my perspective and maybe it can help someone who is on the fence. The choices are vast this year and I wanted to post why I chose the iPad Air as opposed to the mini.
