I thought this would make an intersting comparison of the two extremes of DSLR.
On the left is the Pentax Kx DSLR that we bought for my girlfriend's mother. On the right is my Canon 1D MkIV.
I really like the little Kx even though it is dwarfed by my large hands. It certainly has its purpose as a travel camera with some pancake primes, although the lack of focus indicators in the viewfinder is a pain.
In case you are wondering the lenses are the smallest pentax and canon lenses I have. The Tokina EL 28mm f/2.8 on the Kx and the EF 15mm f/2.8 fisheye on the 1d
