The O2 XDA Stellar was a prominent device announced in November 2007, offering a glimpse into the future of mobile computing. Although it was eventually cancelled, its specifications and features remain a testament to the innovation of its time. The device ran on Microsoft Windows Mobile 6.0 Professional and was powered by the Qualcomm MSM7200 chipset, delivering a powerful performance for its period.
Design and Display
The O2 XDA Stellar had a distinct design, characterized by dimensions of 112 x 59 x 18.6 mm and a weight of 190 grams. It featured a robust build with a QWERTY keyboard, providing both tactile feedback and a sense of familiarity to users accustomed to physical keyboards. The display measured 2.8 inches with a resolution of 240 x 320 pixels, boasting a screen-to-body ratio of approximately 36.7%. The TFT resistive touchscreen could display 65K colors, offering a basic yet functional visual experience for mobile users.
Performance and Hardware
Under the hood, the XDA Stellar was equipped with a 400 MHz ARM 11 CPU and an Adreno 130 GPU. Such specifications, though modest by today’s standards, provided ample power for running Windows Mobile applications and facilitating general usage. The device supported 128MB of RAM and 256MB of internal ROM. Additionally, it included a microSD card slot for expandable storage, ensuring users had flexibility in managing their data and applications.
