Hard to swallow pill: This will probably get tweaked and eventually be very successful. Most people do not like or know how to mess with settings on their phones. You, on this website, are probably an exception but deep inside you know that. How many friends and family members have you had to explain how to change something on their phones? How many have you noticed that NEED to change something on their phones but didn't even know it, much less think to ask? Now think of all the people whose phones you've never even seen.
Of course I'd love to see it go the way of touchscreens in cars where consumers reject it, but I just don't see it. Assuming they can get it to where it does the 5 or 10 tasks the average user would want to do, this will probably be the new norm moving foward. Don't believe me? Look at modern macs or windows and how many settings they hide.
