congrats, by far the best phone I've ever had. I was a regular at crackberry.com, now I'm on here constantly. A couple of tips for you new guys with it (had mine since May). First, it will never get the battery life your BB had, but if you turn it off every night when you charge it, and turn it on in the morning, it should last you the whole day without a problem. I've had crazy issues with charging and times it has lasted, and this is the best I've come up with. Bump charging and that crap is a waste of time. If you used to have your bb shut down overnight automatically, then this will not bother you.
Second, DO NOT use a task killer. VZW seems to recommend them, and I used it too in the first month. Having a BB I was so used to making sure apps closed down so it didn't eat my memory or wear down the battery. Android does this for you. If you find an app down the road that never shuts off, you might think about getting rid of it. Task killers have used more battery than they saved for me.
For those who were addicted to bbm, pingchat has just become official for android. Your bb friends can use it too, but it is not in the bb app world yet ( my wife is still using a bb). It is the best replacement I have found for bbm that works well, plus it works across all platforms (bb, iphone, android).
The last tip I can give is to use wifi whenever possible, and turn off 3g when using wifi. It will work much faster and save you a ton of battery life. Just be sure to turn it off when not in range of a wifi router, but on screen widgets make that a snap. Enjoy your new toy!
