I only have a compact panasonic lumix at the mo - 7Mp. took it out today and tried the same pic with and without a tripod. I couldnt see a difference. Are tripods redundant in this age of 'image stabalisation', 'vibration reduction' and software which can easily realign your horizon?
The reason why you couldn't see a difference was that your shutter speed was fairly fast, which allowed you to handhold the image. Along with the IS system to steady your shot.
If your shutter was something like 1/4, then you might notice the camera shake.
But I don't think tripods are, or ever will be redundant.
