Well, If I am looking correctly, he is looking at a VL not a VI-L. The VL and L1 are relatively the same camera. The VL having a self timer, metal curtain I believe and a cool colored RF patch of the later VI series cameras. Neither have framelines, but both have the variable magnification finder mentioned above, a pretty nice feature. In the cameras I have and have handled, the warm toned finder patch like that in the L1 has always been better defined and easier to use than the cooler tone patches of the later V series and VI series cameras. Between the cameras you are looking for question about the clearness of the finders and definition/contrast of the finder patch.
The 7 is another ball game. Designed totally independent of Canon's prior cameras and pretty well done. I always imagined them to be bigger than their older siblings, but they are not, just about the same size, any differences are measured in mm not feet. I do not yet have a 7, but anticipate it to be a much more modern design in use and usefulness with the multiple built in framelines and meter, though uncoupled.
