It is old news that the next version of the iOS has hit the streets, but it's worthwhile to measure just how much impact it has. The biggest change is not to the iPhone - as the changes there are merely evolutionary at best. But the iPad - well, after the 4.2 iOS loaded up it was like everything was brand new again. Multi-tasking and folders were the biggest benefits that I saw and quickly embraced. Beyond that the unified inbox is nice and various minor improvements with Safari.
