There's nothing inherently wrong with it, but my inner writer cringes, since it's a random throwback to Jobs' commencement speech, and it seems a bit out of place (especially in contrast to the previous 3 headings). I tried to come up with something short/powerful/meaningful, but in the couple minutes I've spared I've come up empty handed.
I would recommend finding a different background image for your header, as I think you could find something a bit less noisey. I like back5 with an y-offset of 540, but another stars/galaxy image would be great if you can find one available for free!
BUT. It looks great! I really wish it was available for android. Keep it up, this is a win for you to remember :)
