On the first day I noticed much noise on the loudspeaker. The noise could be heard before the connection is established and could not be influenced by the volume setting on the phone. Thus, it was clear that here cheapest amplifiers were installed to play.
However, an absolute no-go for the HTC Desire X is the lack of electronic compass.
It can be used with the Reality Scanner no applications such as Google Street View, Google Sky Map or purchased from me Navigon MobileNavigator.
Conclusion:
compared to the old HTC Desire
+ Extended battery life
+ Liquid OS
+ Good display
- No optical trackball (thus it is difficult to navigate in texts)
- Strong background noise in speaker / headphone / earpiece
- No electronic compass for standard applications
