When comparing "iPad Air 2" and "iPad mini 3" with the past iPad, it looks like this

"Thinner than pencil"IPad Air 2"Touch ID equipped with a new"IPad mini 3So I compared these devices carefully as compared to iPad and iPad mini that were released in the past.

◆ Comparing the past iPad
From left to right, this is the first iPad, the new iPad (3rd generation iPad), iPad Retina display model (4th generation iPad), iPad Air, iPad Air 2. The iPad 2 is out of hand and the bezel part of the third-generation iPad is more yellow than otherGlazed cracked when you hit with a hammerIt is,Repair by yourself using iFixit dedicated repair kitBecause it was.


This is the back.


It is like this when the power is on.


From left to right, this is the fourth generation iPad, iPad Air, and iPad Air 2. IOS 7.1 for iPad and iPad Air and iOS 8.1 for iPad Air 2 are installed, but when you look at the number of applications on the home screen, you notice that the number of applications being preinstalled is different. Three new preinstalled apps added in iOS 8.1: iBooks, Hints and Podcasts.


This is when I arrange the first iPad (left) and the latest iPad Air 2 (right). Both are 9.7 inch displays, but the iPad Air 2 does not look like the same display size because the bezel becomes narrow and it is compact.


The display resolution of the original iPad is 1024 × 768 (132 ppi)


The resolution of the iPad Air 2 is 2048 × 1536 (264 ppi), so it's just 4 times the resolution of the original iPad.


From the bottom I will arrange the first iPad, 3rd generation iPad, 4th generation iPad, iPad Air, iPad Air 2 from the bottom. Earphone jack and power button are arranged on the top surface part from the first generation.


Positioned on the bottom is a port for charging the internal speaker and terminal and synchronizing with the PC. The change from 30 pin port to the lightning port is from the 4 th generation iPad.


There is nothing on the left side surface from the original iPad.


A mute button and a volume control button were arranged on the right side, but in the iPad Air 2, the mute button finally disappeared.


If you look closely well, the volume control button (bottom) of the iPad Air 2 is the same design as that of the iPhone 6/6 Plus (top). The reason why the iPhone 6/6 Plus has a mute button, but not on the iPad Air 2 is a mystery.


When rear camera is lined up like this. If I remember it well, the original iPad did not have a camera.


Although the weight of the original iPad (Wi-Fi model) is 687 g, ....


IPad Air 2 (Wi-Fi model) was 437 g, just 250 g was lighter.


Although it is roughly divided, the design of iPad is changing as "first generation iPad", "3rd generation iPad and 4th generation iPad", "iPad Air and iPad Air 2", but the hard buttons arranged in the device The arrangement of the earphone jack, the port etc has hardly changed, and you can see well that you can use the iPad with similar feeling even if you change the device.

◆ Comparing the past iPad mini
This is from the left iPad mini, iPad mini Retina display model (iPad mini 2), iPad mini 3


New color gold that appeared from iPad mini 3 is on the right.


Home button has evolved to Touch ID only for iPad mini 3.


If you overlap iPad mini, iPad mini 2, and iPad mini 3 from below, this way. On the top is an earphone jack, microphone, power supply lined up from the left, microphones in iPad mini 2 and iPad mini 3 have evolved into a dual microphone.


When arranging cameras like this. In the iPad mini 3, the grooves that were dug around the camera are gone.


There is no change in the design of the lightning port on the bottom and built-in speaker.


There is nothing on the left side of iPad mini.


Mute button and volume control button on the right side.


Let's compare the display resolutions of the three iPad mini. IPad mini's display resolution is 1024 x 768 (163 ppi)


The display resolution of iPad mini 2 is 2048 × 1536 (326 ppi)


IPad mini 3's display resolution is 2048 × 1536 (326 ppi)


The three iPad mini are the same size as 200 mm in height x 134.7 mm in width, but the iPad mini is 7.2 mm in thickness while the iPad mini 2 and iPad mini 3 are slightly thicker than the thin 7.5 mm .


Since the weight of iPad mini is 308 g (Wi-Fi model) and the weight of iPad mini 2/3 (Wi-Fi model) is 331 g, it was lighter than the first iPad even if two sets were combined.
