The 2011 version of the iPod touch Generation 4 was identical to previous versions of the iPod touch Generation 4, except it was also offered in white, like this example.
Although the iPod touch Generation 4 has a design similar to the iPhone 3GS, its features more closely resemble those of the iPhone 4 that sold at the same time. (The iPod touch lacked the iPhone 4 features of 3G/EDGE phone, A-GPS, and digital compass.)
The iPod touch Generation 4 included a 3.5-inch Retina Display (960×640 at 326 ppi), FaceTime video calling (using Apple ID), an integrated microphone, front-facing VGA camera, 3-axis gyroscope, and a 720p camera (lower quality than the iPhone 4). The iPod touch Generation 4 also allowed iMovie editing using the iOS version of iMovie available at the time.
The iPod touch Generation 4 used the Apple A4 processor, 256 MB of RAM, and was available with 32 or 64 GB of RAM for internal storage.
The Generation 7 iPad differs from previous base iPad models with its larger 10.2-inch screen at 2160×1620 (264 ppi) (the Generation 6 iPad had a 9.7-inch screen) and the addition of the Smart Connector. The Smart Connector allows this iPad to use an Apple Smart Keyboard. This iPad was available in three colors: white front with a gold back, white front with silver back, and black front with a Space Gray back. This example is Space Gray.
The Generation 7 iPad uses the Apple A10 Fusion processor with 3 GB of RAM, and has 32 GB or 128 GB of internal storage. It also has an 8 Megapixel iSight camera on the back (1080p) and a 1.2 Megapixel FaceTime camera (720p) on the front. Wireless connectivity includes 802.11ac Wi-Fi and Bluetooth 4.2,. Its two wired ports are the Lightning port and a 3.5mm audio port. Internal sensors include accelerometer, gyroscope, ambient light sensor, compass, and barometer.
Aside from this Wi-Fi model, three Wi-Fi/Cellular models are available (US/CA, Global, and China).
The Siri Remote was released in 2015 along with the Apple TV Generation 4. This remote had a glass trackpad, two microphones, and five buttons. The buttons included Menu, Home, Siri, Play/Pause, and a combined Volume up/down button. This remote used both IR and Bluetooth to connect to the Apple TV. The remote also included two sensors for gaming, an accelerometer and a gyroscope.
The finishes of the remote included a matte finish on the trackpad and a smooth, glossy finish at the bottom. The textured finishes helped differentiate the orientation of the remote when using it in the dark or by touch.
The trackpad on the Siri Remote supported limited gestures, including swipe, click, and tap.
Unlike earlier Apple Remotes, the Siri Remote used a built-in rechargeable Lithium Polymer Battery that charged using a Lightning port at the bottom.
The design of this remote was slightly revised after initial production. The original design had a solid black Menu button. The revised design added a white raised ring around the the Menu button.
The Apple Watch Series 4 was the first major redesign of the Apple Watch family and added several important functions, including health-related features. The display was over 30% larger and filled the entire screen with curved corners, it added more advanced input capabilities, more powerful processing, and more advanced sensors. This model also included GPS and cellular service for use in the United States and Canada.
Like all cellular-capable Apple Watch Series 4 models, this watch could connect to the Internet without an iPhone and send and receive phone calls with an activated cellular service. It was controlled with a Digital Crown with haptic feedback and Force Touch.
This Apple Watch Series 4 model is 44 mm (previous Apple Watch models were 38 mm and 42 mm) with a 368×448 OLED screen. This stainless steel case model used a sapphire crystal to cover the display. All Series 4 models used a ceramic and sapphire crystal back to connect to the wireless charger.
The Apple Watch Series 4 shipped with “revolutionary health capabilities, including a new accelerometer and gyroscope, which are able to detect hard falls, and an electrical heart rate sensor that can take an electrocardiogram (ECG) using the new ECG app.” When announced on September 12, 2018, the ECG feature was not available until it was released on December 6, 2018, through an iOS update.
The ECG feature on Apple Watch Series 4 marked “the first direct-to-consumer product that enables customers to take an electrocardiogram right from their wrist, capturing heart rhythm in a moment when they experience symptoms like a rapid or skipped heart beat and helping to provide critical data to physicians. The irregular rhythm notification feature on Apple Watch can now also occasionally check heart rhythms in the background and send a notification if an irregular heart rhythm that appears to be atrial fibrillation (AFib) is identified.”
In addition, a new accelerometer and gyroscope could detect falls and automatically call 911.
There were 12 different options for this particular Apple Watch Series 4 model:
silver aluminum case with white Sport Band
silver aluminum case with seashell (gray) Sport Loop
gold aluminum case with Pink Sand Sport Band
gold aluminum case with Pink Sand Sport Loop
space gray aluminum case with black Sport Band
space gray aluminum case with black Sport Loop
silver stainless steel case with white Sport Band (this Apple Watch)
silver stainless steel case with silver Milanese loop
space black stainless steel case with black Sport Band
space black stainless steel case with black Milanese loop
The iPhone 4 represented a major design leap from the previous models with an all stainless steel body, a 3.5-inch Retina display at 960×640 (326 ppi), a chemically hardened “aluminosilcate” over the front display, and the chemically hardened black glass back. A white option was announced, but did not ship for over a year after the announcement.
The iPhone 4 was the first iPhone with dual front and back cameras: a 5 megapixel HD video/still camera (720p at 30 FPS), a 5X digital zoom, and an LED flash on the rear; and a VGA-quality video/still camera on the front designed for video conferencing over Wi-Fi using FaceTime. Both cameras used noise-cancelling microphones.
The iPhone 4 was powered by an A4 processor and added additional mobile network support. It included a digital compass, GPS, an accelerometer, and a new 3-axis gyroscope.
