After installing IOS5, I noticed I had 15 app updates waiting.  So, I hop over to the app store, click the “Update All” button, and set my phone down fully expecting a 15 minute update, one app after the next.  Then, to my pleasureful surprise, I see blue on 6 progress bars on my home screen.  I then slide to the right one screen and see 4 more blue bars.  That’s right, 10 apps are downloading and updating simultaneously.  This is a great improvement over the former single threaded update pattern.  Thanks for the nice new feature Apple!  Now if you’ll just unblock Siri for iPhone 4 users, we’ll really love you.
