I am just about to send my N810 away with the exact same symptoms as listed in this thread. I tried removing my screen protector - no joy. For about a week I was able to delay the inevitable by squeezing on the right-hand side with the keyboard closed. Now, no response opened, closed, or half-way.

One thing I am concerned about is the possibility of this reoccurring after my warranty period is over. I imagine this would not be an excessively expensive repair, but having to do it a couple of times out of warranty would be hard to justify, cost-wise.

Has anyone been able to get a feeling from the repair people about whether this is just a problem with early units, or a batch of parts, or just general wear? I had a clamshell Zaurus before the Nokia, and I had to replace a ribbon cable but that was after a few years.
