Design and Build
The O2 XDA mini S measures 108 x 58 x 23 mm and weighs 160 grams, making it relatively compact and portable for its time. The design features a sliding mechanism that reveals a full QWERTY keyboard, which was a standout feature in an age before touchscreen typing became ubiquitous. Constructed with a sturdy form factor, the device balances functionality with a practical design ethos. The physical keyboard is particularly useful for those who preferred the tactile feedback of physical keys for typing emails or messages.
