Pros:

- Bluetooth
- Wi-Fi
- IrDA
- HSDPA
- Internal Memory

Cons:

- No GPS
- Photocamera could be better
- Phonebook isn’t very organized
- Rather delicate model

Conclusion:

The Nokia E51 is probably one of the models that offers the best price/performance ratio, even if perhaps the design isn’t one of the most fascinating. It features all the possible connectivity solutions, also VoIP support, and its internal memory (which is expandable) makes it a rather good model for a business use.
