I have my main email and my gmail widgets set up to take up a full page on my home page, it's convenient because I can just swipe and see all of my inbox at any time. I know you have music controls in the multitasking bar, but it's not as good as having a fully functional widget for Pandora or Slacker, etc in your notification bar or on your home screen, etc. I don't use either one anymore though, so meh. The Circles widget on my RAZR HD is incredibly useful though (it's on the Atrix HD and RAZR M too I believe).
I don't want to just hate on Apple though, and it's nice that they do make some minor improvements once a year, but a non-jailbroken iOS device is still years behind Android or even arguably Windows Phone. It is nice for them that there are no fragmentation issues and you generally have the same experience as the next guy. I don't think they should have ever put iOS4 on the iPhone 3G though, it gets slowed down too much (same with Jelly Bean on my Xoom, sadly). Whited00r on a 3G is pretty cool.
