Conclusion
The O2 XDA Zinc stood out during its time due to its business-focused features, such as the QWERTY keyboard and PocketPC operating system that catered to professionals who needed to stay productive on the go. Its robust design and practical features laid the groundwork without the frills of consumer-focused devices. However, the device's bulk, limited RAM, and now-antiquated operating system render it largely a relic of technological history. At launch, its price of around 240 EUR was a reasonable cost for those seeking robust mobile connectivity paired with professional tools.
