Shame but X & S will fade into the background. Only saving grace imho is that the One S is a great phone just lacking in storage space. The One X is a bit of a lemon and I think HTC know this (nice screen however) I so wanted the X to kick arse but compared to say the S3 it kinda misses the mark.
It's a pretty good phone really. I have issues with signal dropping but reconnects pretty quickly, though it is so variable. Other than that I've had none of the issues others have had so maybe been lucky. I did hope the signal issue with both the S and X might be resolved.
This can be an issue if I'm downloading a large file as it seems it still disconnects once it's gone into standby, other than that it reconnects straight away when woken up. Mobile network signal is rubbish too for me. Better than the One S but still pretty poor none the less. Sometimes loses 3G/H and either a reboot or airplane mode required to force it back on. This can be an issue when on Three who are 3g only. 
Cmon, its still one of the highest performing most feature rich phones out there. I've had no issues with mine other than living in an area with poor reception.....
Ditto signal but better than the One S it replaced though not as good as the Desire I used to have too.
