I read an interesting article on WM Experts this morning, that eludes to a ROM update in the works. I'm not sure what this ROM would include, but I hope it addresses button responsiveness & improves battery life.

They also discuss the fact that HTC both acknowledges a heat issue & the root cause being the absence of a heat shield. Fortunately they seem to have resolved this on the Touch Pro, but that doesn't help those of us with Diamonds. This could drastically decrease the longevity of our devices, if this is the case, as heat is the enemy for electronic components.

Here's a link to the article.
