I love the way people are getting excited about getting ~9 hours' use from their phone. to me, that means that you no longer have a properly mobile phone as it needs to spend a good proportion of its life plugged in and static.
Anything less than 2-3 days batterly life and I dismiss it out of hand. I don't want to be stuck on site somewhere in the middle of nowhere only to discover that my shiny toy with angry birds on it can no longer work as a phone.
