The first iPad Mini in october 2012 had the same characteristics as the iPad 2. The majority of applications today only work on iOS/iPadOS 10 and next. This means no more possible updates to iOS and the eventual obsolescence of applications that developers cannot keep backwards-compatible indefinitely. Initial iPad1, historical tablets some of which have traveled thousands of miles for several years, are no longer supported by Apple, just like iPad 2 to 4 and iPad Air 1st generation. History : from iPad 1 to iPad Air 2 (2010-2015).There are now countless versions : 21 total models since 2010 in 10/11″, 6 in 12.9″, and 6 Mini 8″. Models 13″, heavy and expensive, respond more to use on the chart table than to mobile use on board. Since 2016 devices benefit from a laminated screen antireflection multicoated and a LED backlight, which allows fairly correct daylight reading, especially with a sun visor added to the case. The screens Liquid Retina high resolution became widespread and provide excellent definition on raster charting and satellite imagery. I will take an iPad Mini on a 18-25 feet, but beyond the distance between the helmsman and the location of the iPad justify maybe a screen 10 inches screen for easier reading. The size and screen resolution : iPad (10-11 inches) or iPad Mini (± 8 inches), I would say that the choice depends mainly on the distance between mariner and screen.Beware though : if you store your travel pics and videos, if you add music and movies, 256 GB or more will not be too much. But if you use raster charts, larger than the vector charting for equivalent area, therefore 128 Go are unmissable. For a strict navigation use, with applications using cartography vector, 64 Go could be enough to go around the world. Storage memory : at 32 to 512 GB depending on the version and up 2 TB for the latest "Pro", the choice is wide.With a single Wi-Fi model, you must add, either GPS Bluetooth, either multiplexer to fetch NMEA data from the on-board GPS, which limits the use of the tablet. Model : I have mentioned it several times in my website ( ²) and several entries ( ³), model Wi-Fi + Cellular is imperative to be provided with GPS. There are several, which does not only depend on marine use, but also the home use of your tablet. The great novelty of all these devices is the appearance of the USB-C connector imposed by the European Union, and the supply of the USB-C charger and cable. With the presentation of the last two iPads this 18 October 2022, the chipset Apple Silicon M2 comes up on models iPad Pro 11″ and 12,9″, with 8 or 16 GB of RAM of RAM memory (depending on storage capacity). The new iPad 10 " low cost" receives the A14 Bionic chip from the iPad Air 4 with a screen extended to 10.9″. Each year it is advisable to review this question, and sometimes more often. Unfortunately having no time to respond to every request a post is required. Many of you ask me about choosing an iPad for boating use.
