The handsets have a classic Sony Ericsson design, with a large screen and responsive, tactile keypad with a sleek and stylish dual front phone design.    Turn the phones horizontally and there you have a digital still camera. Simply slide the active lens cover downwards and a user interface similar to that of a Cyber-shot™ camera automatically appears.
 
A completely new feature developed by Sony Ericsson is BestPic™.  Press the shutter button once and get 9 full quality 3.2 megapixel pictures to choose from in a time sequence – 4 pictures before and 4 pictures after the actual image you captured.  All 9 pictures are displayed as icons on the display. Simply scroll backwards and forwards through the 9 images and save the ones you like best.
 
The K800i and K790i offer full support for a complete digital imaging lifestyle. Both phones support PictBridge™, a feature that transfers pictures directly to a printer by using a USB cable. The phones also are among the first to feature fully integrated Picture Blogging. Blogging is growing exponentially as a way of sharing personal experiences with words and images, and Picture Blogging in K800i and K790i allows users to create and update personal blogs directly from the phone in just a few clicks.
 
Business users will find the K800i and K790i valuable work tools while out of the office and the sleek Velvet Black casing fits neatly with the professional image. Full HTML browsing with RSS feeds and Google Search give you high-speed, graphic-rich Internet use. Support for standard push email and a connectivity suite comprising Bluetooth® 2.0, USB 2.0 and Memory Stick Micro™ (M2™) means that keeping in touch is effortless.  A complete entertainment package including music player, 3D gaming and an RDS FM radio are also provided for business downtime or relaxation.
 
Meanwhile, the new W300i Walkman® phone allows new users to enjoy the Sony Ericsson mobile music experience. 
 
Sony Ericsson has now launched a total of seven Walkman® phones, targeted at different customer needs and lifestyle choices.  From high-end UMTS models aimed at users who want to enjoy over-the-air downloads, high-speed email and Internet connectivity to models targeting more casual music listeners such as the W600i and W800i, Sony Ericsson aims to create a Walkman® mobile phone for everyone, everywhere.
 
The W300i Walkman® phone, which supports both MP3 and AAC music files, offers a great sound experience with up to 30 hours of music listening. The user experience is enhanced by direct music keys, shuffle function, as well as an in-built FM radio with RDS and flight mode.  Disc2 phone software supplied with the phone, allows users to easily transfer their favourite CDs to their mobile phone and enjoy them anywhere, anytime without missing a call. 
 
Featuring expressive colours and a stylish compact design, the W300i is shipped with removable 256MB Memory Stick Micro™ (M2™) expandable to 1GB, as well as a stereo headset, USB cable and music management software. 
 
In addition to the great music features, the W300i offers an easy way to take and view great snap-shot pictures or record videos using the integrated camera with 4x digital zoom.  The phone’s 262K TFT colour screen makes it perfect for taking fun snap-shot images and enjoying them on the screen, while full MMS support enables these images to be shared with friends and family.
 
The monochrome 1” sub display on the outside of the clamshell allows users to view media player information or caller display without opening the phone. 
 
The W300i is equipped with EDGE Class 10 technology, to allow quick and easy data transfers and Internet access, as well as Bluetooth™ ideal for sharing data with other Bluetooth-enabled devices.
