The 1 gig plus upgrade is done (flawless process) and Apple has used their usual approach which avoids the “oh my gawd it has changed so much I don’t know where to start” user reaction. I like most of the changes and really appreciate the multitasking improvements. 

I really like leaving a frequently used app running in background while doing something else and a swipe from right to left brings the app into a split screen. 

After using iOS devices for a couple of years I am starting to use Siri occasionally. While I feel stupid taking to my devices I confess to being astonished at accuracy and what can be accomplished by voice. Voodoo.
