I have a full PC for work, and a Laptop for downstairs, but for traveling.... I use a Microsoft Surface. It's a tablet that is a full PC. I use the Surface at home as a tablet, but also have it hooked up to a monitor at it's own work station. It's great for traveling - small, take it on the airplane, etc.....
This is my Surface in my master bedroom - that's the Surface on the right, and a monitor hooked up on the left.
