If you follow directions about charging/discharging your battery so you don't kill it prematurely you should have no worries.

Overcharging aka (cooking) or completely discharging the battery a couple of times will kill it early - otherwise you should get years of use out of the battery.

At which point your warranty should be expired and opening the case to change the battery would not be an issue.

I imagine it would be similar to replacing a Macbook Air battery which is also not supposed to be user replaceable either.

Excellent advice, thank you! Of course when I called Apple about it, they said I would have to ship it in for them to do it and I would have my computer back in a week or so. My goodness, who wants to do that?

This looks very doable and puts me at ease.
