Allan, one small feature they dropped when they made the G9 is the ability of the LCD to flip out on the G9.  Jerry Webb has an older Powershot and liked this feature a lot. 

I'd probably never use that feature anyway - about the only thing I use the LCD window for is to show the menu while making adjustments. Once in a while I will check it to make sure my composition is adequate but on all the digital cameras I've used (including the D200's) the quality of the LCD window image is so poor you can't see if the image is sharply focused or even properly exposed.

If I am in doubt about my exposure I just bracket the the shot with frames taken one third and two thirds over and under what the camera recommends (one-third of an F stop is the finest adjustment increment available with my Nikons). It's fast and easy to do without taking the camera away from your eye - the D200's controls do it like the F5's did. You can do a lot in Photoshop to correct exposure but it's faster and easier for me to just bracket an image.
