I'm sure that people are concerned about the replacement. My last laptop I bought two or three new batteries for as the old ones wore out. Good to know that battery replacement labor is free, but I'd argue that $129 is a little pricey. Not a lot, but some. Then take into account that you have to take it somewhere rather than just swap it out.

Seems an odd design choice. I'm sure it was intended to reduce size, but still.
