After the release of iOS5, I am actually interested in having an iPhone again. I have been very happy with my DroidX this last year and went with Android because I felt it provided more features and cloud services than the iPhone offered (plus the availability of rooting which has provided me hours of geek out play!)
LifeHacker has an article showing how we in the Android world have had the best features of iOS5 already on our phones and how to get them.
That being said, Siri, the contextual interactive voice feature on the new iPhone 4S, looks pretty amazing and I really want to play with it.
Additionally, here is a news story about 6 free Android apps that are iOS5 alternatives. Did I mention they were free?
