Heh, I feel the exact same way. I love the keyboard, but the phone has far too many problems.
I installed less than 10 apps on internal memory before I ran out of space. Even after installing every app on the SD card, I have less than 20 MB of space left.
The Dialer issue and the fact that my phone loses 40% of battery overnight (even without the Dialer problem) is also extremely worrying.
The phone is otherwise riddled with other small bugs. Universal search doesn't really work properly; I can't search my contacts/messages/any HTC app unless I change "All" to the specific app. The HTC web browser doesn't seem to support bookmarks properly.
This phone would be almost perfect if it worked properly (and didn't have a Facebook button, but that's a minor annoyance only).
I'm going to make a trip to the HTC service center. They told me to do that after I emailed them with my problems. But I doubt these issues are specific to my device only, considering the responses in my other thread.
