Open Discussion: Palettes

Today we're going to open the floor, I want to know what everyone out there uses for their palette!  What's your current favorite?  What have you used in the past?  What are you looking to use in the future?  If you've got a question feel free to leave it in the comments as well! 

Think of this as a guided discussion!  If this is a success, I'm hoping to do more in the future!  So let's hear it!  What do you use?
