Wow, I'm psyched at the new features od iOS5!

Some things I like:

IMessage - ability to send text/pictures etc. Via wifi or 3G is nice!

Newsstand - was wondering how you get magazines on the iPad! This solves that problem

Pc-free- ability to sync wirelessly!!

And other updates like the lock screen update

One thing I don't care too much about is the twitter integration in the iOS
