Apple iPad 2 missing five features look forward to the next iPad 3 add

Apple has released iPad 2, but it is expected that older iPad users will wait for the release of iPad 3.

Although the iPad 2 is equipped with a high-speed processor, two cameras, and more applications, it lacks the following five major features:

1. Retina Display Apple's "retina display" technology was first used in the iPhone 4 and later used in the latest version of the iPod Touch. This is a high pixel density display that is about 4 times the size of a normal display pixel. With a retina display, text content is displayed more perfectly, and developers can add more details.

iPad 2 display resolution with the old iPad. The iPhone 4 uses a retina display for games and applications. On the eve of the launch of the iPad 2, there are rumors that Apple's tablet PC or retina display, and later reported that the iPad 3 or retina display.

2, SD card slot / USB port Apple will position the iPad as the next generation of traditional computer products. However, this does not mean that people can use the iPad to complete the work of traditional PCs. For example, after a camera is connected to a PC, photos can be stored, edited and shared. The solution provided by Apple is to sell the camera adapter and use a 30-pin plug on the iPad to connect the camera to an SD memory card or USB port.

All Apple computers are equipped with USB ports, and the latest MacBook Pro and Air products add SD card slots.

3, Thunderbolt connector Thunderbolt is Intel high-speed port, currently only used for Apple MacBook Pro. The Thunderbolt connector claims to exceed USB 3.0 speed. As the iPad's storage content continues to increase, the importance of Thunderbolt will become more prominent.

4, Near Field Communication Technology (NFC)

There were rumors in early August last year that Apple was testing NFC technology. NFC chips can be used for payment. Apple competitor Google already supports NFC technology in the Android 2.3 operating system.

5, 4G technology The old version iPad only supports AT&T 3G network, iPad 2 adds support for Verizon 3G network. However, Verizon has deployed 4G technology in 38 markets and 60 airports, and AT&T is also actively preparing for the deployment of 4G technology. In contrast, Apple’s rival Motorola will upgrade Xoom tablet users to 4G in the second half of this year.
