A big thanks to those who figured out how to fix the unresponsive touchpad. I got a TSU3000 from ebay and yikes only the hard buttons worked. I pricked each of the dark brown contacts with a needle a couple of times and now its working nicely. I worry that living in a humid place will mean the fix won't last long. I have seen one report of 2 years. Any other data out there. I assume the other models don't have this issue as I haven't seen reports on this site.
