Some people just want the update to just work like the Apple slogan "It just works"Why would you do that? The battery drains initially because everything has to be reindexed. Just give it a day or or so and everything will be back to normal. Same thing happens on the Mac. Spotlight has to reindex and that makes the OS run slow after the update is installed initially until the indexing is finished. But then people freak out for no reason and claim the newest update is slow or start changing settings for no reason.
Just give it a few hours at least, sheesh.
I am thinking that I will definately update to 9. I just need to get a friend with a dev account.
