J,
Good points. Especially about the CI verses steel wok; however, there are a lot of CI woks out there sold by other companies so it's not like Weber is the only company to go that route.
Regarding your other points, the pan doesn't have to sit in the hole. You can put it anywhere you want. The hole is just an option that allows you to use the pan without it sliding around.
Regarding the CI grate design, if I had a choice I would have designed the CI grate differently, but that's just a matter of preference. It obviously doesn't work with how you cook your steaks but doesn't interfere with how I cook mine, so I've got no real complaints there. Plus, being able to cook on a cast iron grate that stays in one place and isn't too expensive is nice.
I think the only benefits you might not be seeing "from afar" (as you put it) is it's really nice being able to reach the entire fire grate with out removing the cooking grate. Also, the wire grate itself is a beast. Really heavy duty. For those 2 reasons, I'd totally recommend the basic great over the standard if someone is thinking of replacing a worn out stock grate...even if they don't plan on getting the other parts.
