I may sound like I'm nit picking, but DVI isn't all digital. DVI-I has analog and digital. DVI-D is just digital. And believe it or not, DVI-A is analog only. You'll find DVI-I mostly on video cards. Thats why you can put a DVI to VGA adapter on them. The DVI-D shows up on monitors. And I have no idea what the DVI-A are used for.
But yes the big advantage is larger screen resolutions than VGA can provide, especially with DVI dual link.
The way I see it, VGA is a holdover from the days of CRT monitors. Manufacturers put it on a video card so you could use your old CRT. And it showed up on early flat panel screens so you could use your old video card that may only have a VGA out. Now you'd be hard pressed to find a video card that doesn't have a DVI connector on it, and any decent sized monitor has a DVI input on it. Ditching the VGA signal on a video card gets rid of all the circuitry required to generate the analog signal and gets rid of a potential source of noise of interference with other components. It makes video card design easier so i can see why they would want to ditch it.
