A good 1:1 program should be like oxygen. It becomes so ubiquitous that you start to forget it's there. Students and teachers begin to blend the use of technology into their daily routine in a way that becomes so seamless that it feels natural. Taking the technology away would be almost like taking oxygen away. You don't notice it until it's not there.
How do you get to that point? Obviously the important infrastructure needs to just work. Wifi needs to be robust and ubiquitous. Servers need to be fast and responsive. Computers and devices need to be simple to use. Software needs to be intuitive and flexible. All that is important, and need to be the first priority of the IT teams that put those things in place. But once those things are in place, we need to stop talking about them.
Learning should be the goal of a 1:1 program. Not devices or wifi or policies or "the cloud". That stuff is important, sure, but the primary focus of a school needs to be on learning, not technology.
In the excitement of putting technology into schools, it's amazing how often we overlook that.
