Cameraphone

Cameraphone - type of mobile phone which has a camera built in. The world's first camera phone was the J-SH04 made by Sharp Corporation and went on sale in Japan in November 2000. The cameras typically use CMOS image sensors. This is due largely to reduced power consumption compared to CCD type cameras, which are also used. The lower power consumption prevents the camera from quickly depleting the phone's battery. Major manufacturers include Nokia, Samsung, Motorola, Sharp Corporation, Siemens and Sony Ericsson. As of 2004, the resolution in Japan is typically in the megapixel range such as 2 megapixels, in Europe 0.3 megapixels is most common. In 2004, 60% percent of mobile phones in Japan have built-in cameras, and this is expected to rise to 100% in 2005.

As a network-connected device, megapixel camera phones are starting to play significant roles such as crime prevention, journalism and business applications as well as individual uses. On the other hand, they are prone to abuse such as voyeurism and invasion of privacy.

Creative Zen

The Creative Zen is a line of digital audio players produced by Creative Technology and a branch off the earlier Creative NOMAD brand (the other branch being the MuVo series). They are capable of playing WMA, MP3 and WAV audio files. The Zen Nano, V, and Neeon series use flash memory. The other models use notebook hard drives (1.8 and 2.5 inch) or MicroDrives.
Models of Zen: Zen MicroPhoto, Zen Vision, Zen Vision M, Zen V (and the premium Zen V Plus), Zen Neeon 2 and the Zen Vision W. The Zen Nano and the premium Zen Nano Plus are flash-based players and is a re-branded MuVo Micro N200.

Ipod

iPod is a brand of portable media players that is designed and marketed by Apple. Since October 2004, iPod sales have dominated the market for digital music players in the United States. Devices in the iPod range are primarily digital music players, designed around a central click wheel — although the iPod shuffle has buttons only. The full-sized model stores media on an internal hard drive, while the smaller iPod nano and iPod shuffle use flash memory. Like many digital audio players, iPods can also serve as external data storage devices.
In addition to playing music, iPods with display screens can display calendars, contact information, and text files, and play a limited range of games. Models introduced in 2004 include the ability to display photos and the fifth-generation iPod, introduced in 2005, can additionally play video files. In January 2007, Apple announced the iPhone, combining the features of a video-capable iPod with integrated mobile phone and mobile internet capabilities.
Apple's iTunes software is used for transferring music (as well as photos, videos, games, contacts and calendars, for models that support those features). As a free jukebox application, iTunes stores a comprehensive library of music on the user's computer and can play, burn, and rip music from a CD. It can also sync photos and videos.
Apple focused its development on the iPod's unique user interface and its ease of use, rather than on technical capability. The iPod is currently the world's best-selling range of digital audio players and its worldwide mainstream adoption makes it one of the most popular consumer brands. Some of Apple's design choices and proprietary actions have, however, led to criticism and legal battles.

Battery life
For example, the fifth generation 30 GB iPod is advertised as having up to 14 hours of music playback.

iPod batteries are not designed to be removed or replaced by the user. Some iPod users have been able to open the iPod case themselves, usually following instructions provided by third-party vendors of iPod replacement batteries. However, the procedure can be tricky, and is poorly suited for people who are uncomfortable working with electronic components. Compounding this problem, Apple initially would not replace worn-out batteries. The official policy was that the customer should buy a refurbished replacement iPod, at a cost almost equivalent to a brand new one. All lithium-ion batteries eventually lose capacity during their lifetime and this situation led to a small market for third-party battery replacement kits.

Playstation portable (psp)

The PlayStation Portable (PSP) is a handheld game console released and manufactured by Sony Computer Entertainment. The PlayStation Portable has the ability to play video games, watch videos, listen to music, view images, as well as Internet browsing functionality (!!!).
PlayStation Portable's audio player supports a number of audio codecs, including AAC, MP3, and WMA, and has the option to be played with or without a set of five visualizations. The image viewer will display several common image formats including JPEG and PNG.
MPEG-4 and AVC video formats are also compatible with PlayStation Portable. With reasonable video and audio bit-rate settings (a resolution of 320×240, a video bit rate of 500 Kb per second, and an audio sampling rate of 22050 kHz) a 22 minute video file is roughly 55 MB, enough to fit on a Memory Stick Duo as small as a 64 MB. At the same rate, a hundred-minute feature film can fit on a 256 MB Memory Stick. Many movie files, both free-to-distribute and copyrighted, have been encoded for the PlayStation Portable and are available on the Internet. Game and movie trailers are increasingly available, even from the studio's official site.
There are numerous software applications and hardware devices specifically designed for PlayStation Portable's various media-centric applications.
Battery life
PlayStation Portable's default battery life varies widely depending on application from less than 3 hours while accessing a wireless network and having screen brightness on its highest setting to more than 10 hours during MP3 playback with the screen turned off. An extended-life 2200 mAh battery will increase this by approximately 20%. A sleep mode is also available that uses minimal battery power to keep the system's RAM active, allowing for "instant on" functionality when you disable sleep mode.

iPhone

The Apple iPhone is a combination camera phone, PDA, multimedia player, and wireless communication device announced by Apple CEO Steve Jobs during his keynote address at the Macworld Conference & Expo on January 9, 2007. The iPhone will support push e-mail, mobile telephony, text messaging, web browsing, and other wireless information services.
The iPhone, unlike most smartphones, will not include a built-in keyboard or keypad; input is accomplished via a combination of technologies, including a touchscreen with software virtual keyboard and buttons.
The iPhone has a scheduled release date of June 2007.
