I've not looked at the iPad lineup for many years but what a terrible and totally unfocused lineup it is. How do you even justify the existence of the iPad Air when you have a regular iPad? The iPad Pro is there to price gouge naive buyers. Just what is the point of the iPad Mini and all the bizarre and seemingly random screen sizes on offer? It feels like Apple has regressed 30 years with this product line up and every team gets their way and has their product in the marketplace. No wonder buyers are thoroughly confused.
Use the
https://www.apple.com/ipad/compare/ page to see what the actual differences are between models of the same size. The differences between the regular/Air/Pro are meaningful. Pricing is, well, Apple.
Regular: Low-priced model if you don’t want to or can’t spend much.
Air: Better screen, faster chip (likely to receiver longer support), supports more advanced peripherals (pencil, keyboard), higher storage tiers, thinner and lighter, large-size option
Pro: Flagship with all the bells and whistles, even thinner and lighter
Mini: Portable/mobile size (fits in a jacket pocket, can be held one-handed for longer periods), Air-level display. Separate from the regular/Air/Pro lineup due to smaller market share and missing smart connector (otherwise it could arguably be part of the Air line).
Screen sizes/aspect ratios:
13”: optimized for landscape/laptop use, full-page PDF (portrait) and drawing canvas use
11”, 8”: optimized for landscape media consumption (16:9 video) and portrait reading/note taking
I don’t know what’s up with the 0.1” inch differences lately, either Apple thinks it’s a good upsell, or there are actually technical considerations behind it.
To compare with the iPhone lineup:
iPad Pro = iPhone Pro (Max)
iPad Air = regular iPhone (Plus)
regular iPad = iPhone SE
iPad mini = iPhone mini (if it still existed)
