I just looked at the specs of the iPad, and it looks like they only have a 5MP camera in them:

The iPhones are 8MP cameras:

If you are going to someplace like this, where most people are only able to go once or twice, WHY would you take pictures with a 5MP camera, when you can readily get a camera with about 16MP, if not more for the same price!
If it were me, I would want the HIGHEST megapixel camera I could afford, so I could get the highest quality shots!
Now if it is just everyday shots, MAYBE it would be okay!
