Summary
- The Mitac MIO A502 and O2 XDA Comet both feature a 2.7-inch TFT resistive touchscreen with a resolution of 240 x 320 pixels, but the A502 supports 256K colors compared to the Comet's 65K colors, potentially offering better color depth.
- In terms of performance, the A502 is equipped with a 200 MHz TI OMAP 850 chipset, while the Comet has a more powerful 620 MHz Intel XScale PXA 270 CPU, which may lead to better overall responsiveness.
- Both devices have a 2 MP rear camera, but neither offers optical image stabilization or a front-facing camera.
- The A502 has a 1050 mAh battery, whereas the Comet's battery capacity is unspecified, and both lack wireless charging.
- The A502 runs on Windows Mobile 6 Professional, while the Comet operates on Windows Mobile 6.0 Professional, with the latter also supporting Wi-Fi connectivity, which the A502 does not.
