I have the original 18-55mm AF-S DX which came with my D40 kit and love it - it weighs nothing, performs brilliantly, and focuses so close that I can use it as a macro if I want. I decided to get this since I do quite a bit of indoor photography without flash, and wanted some extra stability in low-light, longer-shutter speed situations from the Vibration Reduction which I have on my 18-200mm VR but don't use on my D40 (I use that on my D300, and it almost never comes off). It's performed brilliantly under such circumstances; I can get sharp shots at 1/20, 1/10 and even 1/8 if I'm really stable at the time of the shot - something I couldn't reliably get from the non-VR version. It also helps in the long end (55mm) in uneven light and other times when the VR becomes necessary. In terms of sharpness, light falloff, distortion, and all the other metrics, this lens is as good as, or slightly better, than the original non-VR version. It is also a bit heavier and seems a bit more solid in construction, with a tighter zoom ring and differently-sculpted manual focus ring (with more recessed plastic indentations compared with the original model). I think the addition of VR makes it the perfect lens for the D40, D40x or newly-introduced D60, since its performance is so much better in all metrics and tests (particularly distortion and sharpness) than some of its would-be step-up replacements (i.e. the 18-135, the 24-120, etc.)
If you generally do lots of flash or outdoor photography, and don't tend to experience slower shutter speeds due to lighting issues, or take most of your shots at the wider end of the scale (i.e. 18-25mm) this lens is probably an upgrade that you can either do with or without. In the end the investment is quite small for those few times that VR might save the shot, so I would get one. Granted, VR at this level (i.e not 200 or 300mm) is less about hand shake in daylight, but more about low lighting conditions and longer shutter speeds. As for some reviewer's comments on the default lens speed, etc. - this is a $200 prosumer lens, not a $1,500 17-55mm pro wide-zoom with f/2.8 costing 8 times what this lens costs; for the money, you can't get anything better for a Nikon with this kind of performance.
Additional notes: There is some clunking sound from the VR occasionally when focusing, and there is no hood or lens pouch included, but that's less of an issue if, as most people do, you have a camera or lens bag, and as for the hood, I've never used one and never had a problem; if there's sunglare, I can cup my hand around the lens (since it's so light) and have no issues. I think some people use lens hoods to somehow show off that they're "photographers" or "hobbyist-pros" rather than for the reduction of flare and glare when outside in bright sunlight (sometimes direct, etc.) or under sharp lighting. Honestly, I've seen guys taking indoor shots of artwork exhibits under soft lighting with the hood on.

I agree with other posters that this lens is an upgrade over the non-VR version. It is quite sharp, and the VR is effective, especially at the longer focal lengths. However, I tend to take pictures in very demanding eenvironments with low light and very high contrast, for example, night scenes with street lights as this is one of my typical shooting environments. I noticed something in the shots made with this lens that I never noticed in the kit lens. Ghosting and flare. If it is present in the non-VR version, it is not present in an objectionable amount. People may argue that I expect too much from such a low budget lens, but the non-VR lens doesn't exhibit this. I noticed in the product description that there are no ED elements in this lens compared to the non-VR version. This may partially explain this. I returned the lens and now await the new 16-85mm VRII lens that was just announced as I see the value of VR in this range for the type of shooting that I do. However, if you don't shoot in the above mentioned environment, you will have no issues with this lens and will do fine with it as it is priced quite well. For me, the ghosting and flare was a deal breaker and I don't feel like spending time in Photoshop to fix it.

Great upgrade to the already excellent kit lens that came with my d40. Like the kit lens, this lens has excellent sharpness, a good focal range and it focuses fast. The build is great, a little better then the kit lens. And of course VR!
Unlike the other reviewer, I find the VR very useful. I can now shoot handheld at about 1/15th of a second or slower with no blur. with the kit lens 1/30th of a sec was pushing it. This is great for flashless shots in low light.
The reason I gave this lens only four stars is that it only opens up to f3.5 so it isn't the fastest aperature. But for the price, (you get what you pay for), this lens can't be beat!

I recently purchased this product and it only took me a few minutes to realize that I'm paying for something (VR) that I really don't need. That's why I returned it. Don't get me wrong, the lens takes beautifully sharp photos; but when I tested it with and without the VR function activated, I saw absolutely no difference. Maybe I just have a steady hand, but I don't think that was it. My camera does have a good amount of weight in the body, but I believe (as I had my doubts before buying) that a lens with such a short range does not need VR. It does focus very close which is a plus.

I decided to get the new VR version of the 18-55 kit lens because I love low light photography in bars and city streets.
I found that the VR is not very effective below 1/8 second, while I am pretty good (lucky?)at hand held exposures above 1/8 without VR in the limited focal range of this lens. So, it is really only making a big differance between, say, 1/20th to 1/10th ... not a huge range. Not enough to make up for the slightly higher weight, and slightly larger size than the non-VR origional.
That being said, like the origional non-VR version, this is a GREAT little, light, high quality, versital, walk-around lens.
