I am seriously considering purchasing one of the new unibody MBP's with the new "7 hour" battery. Just a couple quick questions for you all: Do you get 7 hours when you turn wifi off, the screen down to 1/3 brightness, don't use the CD drive/etc, or does it actually last 6-7 hours in normal use (surfing web, screen really bright, backlit keyboard on)? Has anyone experienced a degradation in battery life after a bunch of cycles? I notice apple claims that the new battery will last 5 years, yet they don't warranty it for more than a year. That does not sound good to me. Opinions?
