Even older ones are decent. I have a 4 and it's probably got about 2 days of battery life. I put it on the charger for an hour every morning as part of my routine.
Funny how they define it as a hardcore device for professional/serious use, and then define 'typical usage' as 30 minutes per day for purposes of being able to claim a seemingly absurdly long battery life.
But I guess "about 15 hours" sounds a lot less impressive than "3-4 weeks".
Sure, but considering the "fudge factor" that Apple often applies for their battery life estimates ("casual browsing", etc.) an hour isn't all that much.
