When it comes to text selection, how often do people use it? I ask that in sincere curiosity. I know personally that I only select text once, maybe twice a week on my Palm Pre. Holding shift and dragging through the text works great for me. Perhaps you meant in terms of positioning the cursor? Anywho...
Tactile feedback from keyboards/button has always been an issue with me, but I find that a slight vibration from the phone when a softkey is pressed does the job just fine.
