I don't see any good reason to switch from the P90 to the Canon. It's likely the Canon does have better image quality. But not enough better to justify changing cameras. Plus, your Nikon has a longer zoom range. If you really want something better you should be looking at digital SLRs. That's where you'll see a really noticeable image quality and performance benefit. Otherwise, stick with the Nikon and take lots of pictures. More pictures and learning to know your camera well is usually a better way to improve your photos than buying a new camera
