liquid contact - How is that defined?

I have had two ipod nanos shut down without liquid contact. The first showed no "red" dot. The replacement did after about 60 days use.. Apple refused warranty coverage only on the second one - the replacement they gave me. The only moisture exposure either nano had was from perspiration. I used them soley in the gym. I typically clipped the nano to my shirt collar. I never "washed" them. To clean them, I would spray screen cleaner on a microfiber cloth and wipe the screen with the moistened cloth.

Apple tells me that it will replace the replacement for $75. Otherwise, as long as the red dot is there, no warranty coverage!!! No other alternatives. Seriously, are these things not designed and marketed to be suitable for use during physical activity. There are even exercise apps pre-installed. The store manager told me that there was no method of checking the accuracy of the moisture detection "red dot." Liquid contact cannot possibly be defined as including perspiration.

Does anyone have a handle on this? I know there is a Northern California Federal Class Action case getting underway on the issue.

I paid about $150 bucks for the nano. I used it for its intended purpose and after two months I get to take it back and replace it for another $75. What a brilliant scheme. I should just send Apple a $75 check every two months, and go back to my old Sony CD player.
