Dell with the XPS 13z -- more so the new model though than the old one which is what I have.
System76 with the Lemur (<--- the maybe. They dont fit exactly what i want)
Apple with the Macbook Air.
Now, what do I want? Good screen, good battery life, lightweight, non-plastic casing, backlit keyboard, not a brick, intel GPU is fine.
I got the XPS 13z because it gave me a reasonable screen, 5-6hrs of battery life, a backlit keyboard, a good casing with a gorilla glass protected screen, very lightweight (lighter than the macbook air actually), an intel CPU since AMD is going down the toilet as far as CPU's go, a relatively thin profile so its not an issue to put it in my backpack or suitcase with other things in there.
