Touchscreen Mobile & Sidekick

Samsung Memoir 8 MP Camera Phone, Black (T-Mobile)

Is the Samsung Memoir a high-megapixel point-and-shoot digital camera or a full-featured 3G-enabled smartphone? It's both, thanks to the 8-megapixel lens mounted on the back of the device and support for T-Mobile's HSDPA 3G network (in select markets), which provides fast web downloads and multimedia messaging. It will also keep you connected to your closest friends and family members with T-Mobiles myFaves.

The camera is outfitted with a Xenon flash, 16x digital zoom, video capture capabilities, and six shooting modes as well as easy access to your favorite online photo sharing sites. This touchscreen-enabled phone has a large, brightly colorful 3-inch screen, and it includes Samsung's intuitive and easily customizable TouchWiz user interface. It also offers built-in Assisted GPS (a-GPS) navigation, which allows you to utilize location-based services including turn-by-turn directions. Other features include Bluetooth for handsfree devices and stereo music streaming, MicroSD memory expansion (up to 16 GB), digital audio player and FM radio, access to personal email and instant messaging, and up to 5.5 hours of talk time.

T-Mobile G1 Phone with Google, Black (T-Mobile)


The T-Mobile G1's vibrant, high-quality screen slides open to reveal a full QWERTY keyboard, great for communicating with friends online or using the phone's email, IM and mobile messaging capabilities. As another option for accessing the device, the T-Mobile G1 comes equipped with a convenient trackball for more precise, one-handed navigation. The 3.2-inch touchscreen has a 320 x 480-pixel resolution and a 65K color depth. The T-Mobile G1's touchscreen interface is unique, providing you with a more customizable, interactive touch experience. For example, you can set a signature gesture to unlock the screen (there are 30 million possible combinations). There are also different taps for different types of commands--for example, you can use a short touch to launch an application, or a long press on any screen will give you additional options, similar to that of a right click on a mouse.

The phone has an internal 192 MB RAM/256 MB ROM memory, and it's expandable via optional MicroSD memory cards up to 8 GB in size (a 1 GB MicroSD card comes with the phone).

A touchscreen is a display which can detect the presence and location of a touch within the display area. The term generally refers to touch or contact to the display of the device by a finger or hand. Touchscreens can also sense other passive objects, such as a stylus. However, if the object sensed is active, as with a light pen, the term touchscreen is generally not applicable. The ability to interact directly with a display typically indicates the presence of a touchscreen.

The touchscreen has two main attributes. First, it enables one to interact with what is displayed directly on the screen, where it is displayed, rather than indirectly with a mouse or touchpad. Secondly, it lets one do so without requiring any intermediate device, again, such as a stylus that needs to be held in the hand. Such displays can be attached to computers or, as terminals, to networks. They also play a prominent role in the design of digital appliances such as the personal digital assistant (PDA), satellite navigation devices, mobile phones, and video games.
