Final signs that the tablet has won:

1. Posting from my desk usually means my tablet is between my keyboard, and monitor, and the keyboard is paired to the monitor.
2. If it doesn’t involve video playback, Direct3D games, or compling code, I’m probably going to use my tablet when I’m at my desk more than my desktop.
3. The urge to hook up my HDMI switch again, so that I can share the monitor with my tablet.
