I'm looking for some advice. I'm a beginner photographer and recently purchased a Nikon D3100 and am looking for a good all around lense to purchase. I'm leaning towards the Nikon AF-S DX Nikkor 18-200mm f/3.5-5.6G ED VR II. Any suggestion?
Why did you buy a single lens reflex digital camera over a superzoom point and shoot? Hopefully, one of the reasons was to make better images. One of the reasons you can make better images is because you can buy better lenses designed to do specific things.
Super ratio zooms like Nikon's 18-200 or Tamron's 18-270 are do anything but do nothing very well type lenses. I believe they are going backwards from the reason you purchased a DSLR. The optical compromises that have to go into their design make them so they just can't produce as well as other designs. They are convenient, but hopefully you are not willing to trade image quality for convenience. If you are, you made the wrong decision in purchasing that superb new camera.
Really good zoom lenses tend not to exceed 3x in ratio. Your 18-55 kit lens fits that. Some of the best zooms are lenses like the 14-24, 24-70 and 70-200. Notice they are 2x and 3x zooms. Some of us are willing to go to 5x, 6x and even 7x, but there quality really starts to fall.
My suggestion would be to wait a little and really put some thought into it. Don't let NAS (Nikon Acquisition Syndrome) get the better of you and your wallet. Make sure you really have mastered what you have. Make sure you have run into limitations where you can't find a work around. Maybe you can't reach out to show that bird. Maybe you can't focus close enough to flowers. Maybe you can't wrap your subject around you and show enough depth. Maybe you want better low light characteristics. Whatever it is, know what you need to overcome it. Then and only then decide on a new lens to do what you want to do.
So, my question would be, where has your current gear let you down and you could not work around that limitation? How has your current kit lens failed you? Have you mastered that D3100 and that 18-55 VR lens? Are you ready to master another focal length?
If so let us know. Just don't ask for a suggestion without being armed with this information. The answers you'll get might be meaningless. If you have tried to take a picture of that bird on the feeder and can't get close enough without scaring it and you've tried better stealth techniques and still can't get there, I'd suggest a telephoto zoom like Nikon's excellent 70-300 f/4.5-5.6 AFS VR. I'd not settle for a cheapie in this case. It's not very expensive and is in fact less than that 18-200 you were thinking about.
