So why MAC? In Australia, it is a bit exxy ($33 for a single eyeshadow, and about the same for a liner pencil), but in my opinion, it is very much worth it. I have issues with eye makeup - it tends to either fade to nothing, or walk all over my face (Urban Decay was shocking for this). MAC stays put. I have 4 kohl pencils, and they do not budge, even if I am melting, the e/l stays put.
I used to have a MAC eyeshadow, Vex, which was a colour-change kind of thing, silvery-gold, slight shimmer, with hints of fuschia, gold, green, purple and blue, depending on how the light hit it - it was brilliant! Then it grew legs and walked. I also had an olive creme liner, which I killed.
The other thing I love about MAC is their collections/collaborations are incredibly cool. They've had Hello Kitty, Dame Edna, Barbie, Venomous Villains, Fafi to name a few. Rihanna has collaborated *yawn* and every year Viva Glam is a collaboration with a celebrity to raise awareness of AIDS.

There have been some collections which have left me cold (Alexander McQueen), but for the most part, the quality of the product, and the often awesome packaging (examples below) inspires me to love me some MAC. The thing is, even with the price-point, MAC is worth it for me - Revlon is around $20 for a duo eyeshadow, and it's useless. I'd rather pay a bit more for something I know is going to work, especially as, once it's opened, I can't returni it.
