Trusted Reviews has written up a detailed review of the HTC Kaiser. It gets a full 10 marks out of 10 on features, and overall receives a 9/10. Worth checking out to see what this device has over the HTC Hermes.
With the P4550, HTC has taken what was already a competent smartphone
and thought really hard about how to make it better. The result is a
handset that does pretty much everything you could possibly want a
handset to do.
