Update to the new version the day of release?
Not difficult when there's only one iPhone platform out there. Not the case when Sony, LG, Samsung and others are all out there offering users a more specific and unique experience based on the users having choices. Would be great for me to get Android L at the same time as others, but the reality is just like with Kit-Kat in the interim period lots of updated apps offering similar functionality come about to make the transition smoother and the wait less painful.
Case in point, I have a new notification system, SMS app, Calender and Dialer apps on my Note 3 all based off the L-Platform design. I didn't like the email option but at least I had a choice there too. Functionality and workings within them are great.
