I have an Acer and I must admit I am very happy with it, it is 4:3 and if I was going to replace it then I would get a widescreen, mainly because it is better for video editing.
DVI is certainly better, and a lot of video cards only have DVI sockets on them, mind you they normally put a convertor in the box.
But saying that, I have seen a monitor working on DVI and VGA and there is not that much of a difference.
I want a monitor that turns on it's side, so it is more like an sheet of paper..
It depends on your budget.but if you can go for a 19inch,very nice to use.
