Personally, I like the new vault. I actually hope they take it one step further and expand it to the inventory as a whole.

Having middle aged eyes and a 19" Widescreen monitor at a fixed resolution, I would always have to lean close to it to see what the heck I was looking at.

I mean, seriously, the icons are the size of well, not even a postage stamp. I can't read a postage stamp from 3 feet away.

This way you can read what things are without having to scroll over each one with the mouse.
