I hate to say this, but bullet points are not how you sell consumer devices. This ad looks like the result of a meeting with too many attendees that was too long. You're selling to average people who just want a cool phone, you're not bidding on a government contract. Adjust the style accordingly.
I don't really like Apple's ads, but they seem to work.
