That's entirely your choice. Some people are holding back on the update to iOS 6 because they're jailbroken on iOS 5.1.1 and don't want to lose their jailbreak. That doesn't apply to you. Personally, I updated the day the update became available and haven't regretted it.
Thanks both Marilyn, and Scifan57 for your help. I have update my Ipad2 to iOS6, and hopefully Jailbreak for iOS6 is coming soon.
