Camera - Live View

It seems like most of the leading brands of cameras are taking up live view. For example - Canon 5D MarkII and Nikon D3/D3X and Olympus.

What is live view?
Live view is essentially the tricked up version of the point and shoot cameras for the digital SLR, where the image is displayed on the back display screen.
This has been made possible by moving the mirror so that the image on the back of the camera is as the image sensor sees it.

Why do we need Live View?
Well we probably don't but in a competetive market where one of the leading brands offers it the others follow. So you can still use the view finder to take the shot and if you don't like the live view fuction don't use it or get a camera without it.

Benefits!
As I see it live view can be best utilised for difficult angles where it would be impossible to put eye to view finder. So artsy stuff, low angles, above head. Just look at the display and shoot away!


Negatives!
Probably paying for the privilage of having this function on the camera.

Your Opinion?
Would you get a camera with live view just because it had it?
