In order to prevent any issues or complains from potential customers, Apple already released a TechNote related to the famous non replaceable battery powering the new MacBook Pro 17". As we already announced it after the keynote, the battery can be changed in any APR for 179 Euro, and a one-year warranty will be granted too (depending on the local laws). One will have to wait for couple of months to evaluate if the battery lifetime really evolves according to Apples claims.
