I am not an early adopter when it comes to computing gear. I let the early adopters move first, and then wait for howls of pain or signs of blood. The early adopters have moved, and iBooks have been deemed (mostly) safe. Still, I'm torn. The voice in one ear says to stick with what's familiar, and mummbles about not having a stable working environment for weeks or months. The voice in the other ear says it's time for another learning curve, and murmers alluringly about the pleasures of having a portable *nix.
