My dream setup, then, is a computing world where I don't have to carry at least three computers - laptop, tablet, phone, not even counting cameras and iPod and other oddments - around with me in order to function in the modern world. The world should provide me my computing environment and maintain it for me and make it available everywhere. If this were done right, my life would become much simpler and so could yours. Wow that sounds like a dream!
