Conclusion
The Nokia Lumia 900 AT&T delivered solid performance in a premium design, making a statement with its AMOLED display, decent camera capabilities, and integration into the Windows ecosystem. However, it faced challenges with app availability, non-expandable storage, and modest battery life. For its price of about 160 EUR during its release phase, it attracted users looking for an alternative to mainstream Android and iOS devices. Though discontinued, the Lumia 900 holds historical significance as part of Nokia and Microsoft's ambitious partnership, marking a distinctive moment in smartphone evolution.
