Conclusion
The Eten M550 represents a snapshot of the transitional smartphone period, packing features like handwriting recognition and a PocketPC interface into a single device. Priced around 220 EUR at launch, it catered to a market niche looking for mobile productivity solutions over entertainment or high-speed connectivity. In its time, it was a serviceable device for professional purposes, but by today’s standards, it is more of a collector's piece than a practical phone for everyday use.
