The MI-E25DC, released in mid-March 2002, is the final MI-series Zaurus. It retains the basic design of the MI-E21 but adds an integrated digital camera, making it one of the first PDAs to combine a built-in camera with a slide-out keyboard – but is the first to do so without changing the size of the PDA. The camera-equipped enclosure is slightly thicker, measuring 74 × 138 × 19.8 mm and weighing approximately 190 g without the protective cover – that's three millimetres thicker and two grams heavier.

The MI-E25DC's 3.5-inch front-lit reflective TFT colour touchscreen retains the 240 × 320-pixel resolution and 65,536-colour display of its predecessor, while the internal memory remains at 32 MB (16 MB RAM and 16 MB flash memory), with approximately 15 MB available for user data.

The rear-mounted camera uses a 310,000-effective-pixel CMOS sensor and a fixed-focus f/2.8 lens, capturing JPEG still images at up to 640 × 480 pixels. Images can be stored in the built-in Photo Memory application, organised and edited, and attached to e-mail for sending to a PC or another Zaurus. The device can also resize photographs for J-Phone's Sha-Mail service, making it easier to exchange pictures with compatible mobile phones. A small mirror beside the lens helps users frame self-portraits, reflecting the growing popularity of camera phones and picture messaging in Japan.

The MI-E25DC can also record short video clips in ASF format using MPEG-4-compatible encoding, with a maximum recording time of approximately 20 seconds at 160 × 120 pixels. Video messages can be sent to a PC or another compatible device. The Zaurus retains the MI-E21's multimedia capabilities, including MP3 music playback and video playback in MPEG-4 and Nancy formats. With the optional video-recording card, it can also record television programmes or other external video sources, while the CompactFlash Type II and SD/MMC slots support memory cards and compatible expansion accessories.

Beyond imaging and entertainment, the MI-E25DC has the familiar Zaurus organiser functions, including a schedule, address book, action list and memo tools, together with an HTML 3.2 Web browser and e-mail software. Its CompactFlash slot also supports compatible PHS data cards, enabling mobile Internet access and e-mail away from a computer.

The combination of a built-in camera, image editing, mobile sharing, video recording, music playback and a physical keyboard made the MI-E25DC a distinctive culmination of Sharp's traditional MI-series design, before the company shifted its PDA development towards the Linux-based Zaurus range.
