Manufactured by HTC and marketed by O2, the XDA IIi combined the functionalities of a PDA with those of a mobile phone, paving the way for future smartphones.

Design and Build

The O2 XDA IIi boasts a robust yet sleek design. Measuring 130 x 70 x 19 mm and weighing 190 grams, it was considered a compact and lightweight device during its period. Its build featured a Mini-SIM card slot and came with a TFT resistive touchscreen, offering 65K colors for a vibrant display. The 3.5-inch screen, while small by today's standards, was quite substantial at the time, enabling users to interact with the device efficiently. Its resolution of 240 x 320 pixels offered a decent display and adequate readability, given its 114 ppi density.

Display

The 3.5-inch TFT resistive touchscreen was among the standout features of the O2 XDA IIi. Capable of displaying 65K colors, it provided users with a reasonably vibrant viewing experience. Although the touch sensitivity and response might have been somewhat limited due to the technology at the time, it represented significant progress in mobile device interaction, facilitating tasks like browsing, email, and lifestyle apps through touch navigation.

Performance and Hardware

Under the hood, the O2 XDA IIi was powered by an Intel Xscale PXA272 520 MHz CPU. Though modest by today's standards, this processor was efficient enough to handle the multitasking capabilities of the Windows Mobile 2003 SE operating system. This platform allowed the device to manage personal information management tasks alongside telephony functions, making it a practical choice for professionals.

The device came with 128MB of RAM and 96MB ROM, allowing for reasonable performance of applications and storage of data. Additionally, it included a card slot supporting MMC/SDIO for expandable storage, allowing users to store more data and applications as needed.

Camera and Multimedia

Equipped with a 1.3 MP camera, the O2 XDA IIi was capable of taking basic photographs and videos. While meager by modern standards, it was a relevant feature in a time when many mobile phones still lacked integrated cameras.

On the sound front, it featured a loudspeaker and offered vibration and downloadable polyphonic ringtones as alert options. However, it did not include a 3.5mm audio jack, which meant users had to rely on proprietary connections for audio accessories.

Connectivity

The USB connection was proprietary, which limited compatibility with some USB devices.

Operating System and Software

Running Microsoft Windows Mobile 2003 SE PocketPC, the O2 XDA IIi provided a versatile operating environment for running a variety of applications from productivity tools to entertainment apps. Along with basic phone capabilities, this OS allowed for a full-fledged PDA experience, which included calendar management, contact and email handling, and more, effectively pioneering many features that would become standard in later smartphone operating systems.

Battery Life and Management

The device came equipped with a removable Li-Po 1200 mAh battery, which, while small by modern measures, was adequate for the power demands of the time. The battery provided up to 150 hours of standby time and up to 3 hours and 30 minutes of talk time. Users appreciated the removable battery design, which facilitated battery replacement and extended the device's overall lifespan.
