That's nice. I want to be able to carry all of my files with me everywhere. I want the same development environment everywhere and to only configure it once. I want those configuration changes to follow me everywhere. I want to be able to answer the phone on my desktop. I want to have my call and messaging history accessible no matter what device I'm using. I don't want to buy 4 computers (phone, laptop, tablet, desktop) I want to buy 1. Displays, touchscreens, and peripherals should be dummy passthrough devices. I want all of this to be instant (which means no cloud storage until we can make that much much faster).
You might not want convergence, but I would kill for it.
