The current MacBook Pros — do the batteries really last longer?

Question

On their website, Apple makes a huge deal about their new battery technology that they're using in the MacBook Pro. In actual practice, is the battery performance really better than the previous generation?

Answer 1

Anandtech did an article on the battery performance, you might want to read up the article.

EDIT: Follow-up article to the above, this time with Vista & Windows 7 being used as the OS.

Answer 2

The answer is yes, it does last longer. But you'll only have a definite answer to the number of times it's rechargeable in about 5 years from the production date. There's several reviewers that confirm the 7h life time, among them MacWorld, Anandtech and TomsHardware.
