Pigment vs Pressed Eyeshadows

[Yia]

This year, I want to take the plunge and invest in Pigments starting with the Holiday collection, but here is the rub. I hate mess. The pigment colors though are so vibrant, that I am really thinking about it. I wouldn't invest in the full sizes, but in the sets and I was wondering, for people on both sides (Those who love pigments and work with them and those who don't like them)

(1) What are the pros and cons of working with them for the eye area?
(2) Are glitter Pigment still not recommended for the eye area?
(3) What's the best brush for application when you really want to pack the color in?
(4) Are there any differences between them and the pressed eyeshadow in terms of content, or if I were to grind the pressed eyeshadow would I get pigment?
(5) Is there anyway to turn the pigment into pressed eye shadow?
(6) Is there a top or something that you can get to control the mess?
(7) What's the best way of putting them on without getting fallout?

What would you recommend for a newbie
