Wow, that's really poor quality, I was kind of expecting more from HTC.
This cartainly makes me think twice about buying this device.
I might as well ad that this is not the first time i read about this issue, the pics made this problem so much clearer though. It's also sad to see that this issue actually seem to be so common=/
Too bad that the shell is the only affordable spare part.
Even if the warranty covers this, the buttons has been "worn out" far too fast. So the new ones would be worn out just as fast if they don't do something about the quality. Which I highly doubt that they will, HTC seems to have forsaken this phone a long time ago.
Still, this will be an interesting thread to follow. And after all, the tattoo is still the only android phone that I'd be interested in owning.
