Middle click failure plagues nearly every mouse I've owned, OEM, Logitech, wired, or wireless. I take full advantage of the middle click shortcuts like opening links in new tabs, but I don't think I'm putting it through undue stress either. As far as I can tell, I'm clicking it with the same force as I would the other mouse buttons and much less frequently than the left click.
Failure usually starts with occasional missed middle clicks, which after some point, rapidly progresses until it's failing to register more often than not. At that point, everything else will still work perfectly. No improvement even if I take it apart to clean out what little dirt had accumulated.
One of my mice has managed to avoid this fate far longer than the others but I've just recently stopped using it due to the rubberized exterior turning all gooey and sticky. The only middle mouse buttons that seem immune to all of this are the ones on ThinkPads. Anyone else notice this or could recommend a good mouse that can stand up to a bit of middle-clicking?
As long as you have a strong backup strategy, I would recommend full disk encryption during installation, especially if for a laptop. Peace of mind with negligible cost on modern hardware. Even accessing the encrypted disk from a live USB takes only two extra commands compared to an unencrypted disk. As long as the LUKS header doesn't corrupt, hence the need for good backups.
