shadowdude, Thanks for the explanation. I see what you're saying. I guess that I tend to un-lock my screen and check so often for all sorts of things (emails, phone calls, baseball scores, weather, Facebook, etc etc) that the absence of a notification light doesn't bother me that much.
The other thing to consider is that, most likely, in ANY model of phone there will be some feature we don't like or some spec that we wanted to be better or some missing feature we want. It's always gonna be a bit of a trade-off, no matter what phone one gets. To me, the ability to walk around with such a powerful device in one's pocket that connects us with the world -- with people and with information and with entertainment -- in ways that would have been considered science fiction not very long ago makes me see the glass as 9/10 full, at most 1/10 empty!
