I Use a Macbook Air
Everyone has their weapons of choice. On impulse, I went for a MacBook Air. I use an iMac at work and have always used MacBook Pros at home, the Air didn't do it for me on sight, but I was blown away at it's responsive SSD drive, unibody construction making it sturdier than it looks, weight (or lack thereof) and years later it still performs as it did new. I can't recommend this enough for general portability, daily use and when it comes to travel, it's amazing. I usually have the bigger Adobe art programs running and it's still as nimble as a Porsche Carrera.
