I don't know about the wide angle lense, but my Nikon partner used the 28-200 you had for a while, and just got tired of the poor image quality, and has since upgraded to the 70-200 VR lens. From what he said and showed me, the 28-200 just is a consumer lens that won't deliver ultra sharp and crisp images. The glass in the lens is one of the most important parts of an images clarity and sharpness, and if your glass isn't good, the images won't be either. I'd maybe go to your local camera store and see if they'll let you snap a few shots with a better lens, and take them home and see if you notice any differences.
