i hate when people bring up this topic (3 in last month). 18-200VR IS NOT THE FIRST. the 35-350 and current 28-300mm lenses have been around for several years. nikon only answered canon's film optically stabilized 10x superzoom with their own digital 10x superzoom (both are slightly over 10x, but who really cares). in nikon's case, the zoom is intended to attract p&s customers with an attractive looking 10x range, while canon's 10x zooms are geared towards professionals with very specific needs, especially photojournalism. the 18-200 suffers from many of canon's 17-85's mistakes, but on a much larger scale. distortions are so grave that straight lines in buildings are horribly bent (most reviews will downplay this, but if you look at samples, it's horrible). it has falloff problems, even more CA and edge softness than 17-85, and the vr isn't as good as IS. the cost is also quite high. if you where to go with canon lined lenses, you could get the 17-85 and 70-300 for less than the price of the 18-200 (both with IS) and you would get much better quality (especially in 40-300mm range). did i also mention an extra 100mm reach?
if you are looking to save space with one lens vs two for travel, just get yourself a 10x zoom point and shoot. you'll have a much lower cost, less weight, still keep IS in some models, and it'll cost a whole bunch less too. unless your needs justify it, 10x zoom and slr cameras don't mix well...
btw, i have not talked about third party 1x-x00 lenses because they do not use optical stabilization.
I don't hate macs or OSX, I hate people and statements that portray them as better than anything else. Macs are A solution, not THE solution. Get a good desktop i7 with Windows 7 and come tell me that sucks for photo or video editing.
