Could you be more specific with the issues? I've just bought a Topaz and would like to be able to access (though hopefully not contribute...!) to a list of testimonials to this failure.
A single place where we can notify HTC / service providers of the issue and how widespread it is would be extremely useful, especially considering the weight this community has with the company (Something tells me HTC are very interested in what people here say and do... It's the main reason why I went with an HTC / WinMob mobile phone).
Constructive comments only, though. "OMG AY HEYT HTC LULZ!!11 NOOBZ!1"-style flames achieve nothing.
