The better battery life is one of the FIRST things I noticed when I got my iPhone. When I had my Motorola Droid, I had to bring my charger to work with me. By the time lunch would come around my battery would be around 30-40% or less. I would have to keep a charger. If I left my charger at home, I would have to shut down the internet connection until I needed it (usually at lunch or on break) or my phone would be dead by the time I got off work. I left my iPhone charger at home one day and I just knew that my battery would run out. I was shocked when I got off work and I still had plenty of power left.
Another thing I just noticed. It seems that iPhone's battery also charges quicker than the Droid battery. I could be down to 20% or so and plug my phone up and it seems like after about 15 minutes or so, I'm up to 50% or more. It would take forever for my Droid to charge like that.
I also agree that it seems like the apps are designed better on the iPhone. When I got my iPhone I was glad that I was getting that Facebook app back. I had it on my iPod Touch and loved it more than the one on the Droid.
CJ, you might want to try Facely HD for iPhone. I like it better than the original Facebook app..
