Init Vs. Upstart

my very first post will be about the revolutionary change that Redhat decided to do, changing the boot process from the init method that work in all Linux destros to a new method named "upstart". yet not all the boot scripts and services are transferred to upstart but many of the service move even the init start script are now like a child process that start by the upstart. Redhat declared that the upstart method will decrease the boot time and will make the system more smoother during the start up. i will give it a close look and post a brief about both and the cons of the new "upstart" but i don't think there will be any after all Redhat guys knows what the market really needs.
