The future of technology in education

What do you think is the technology we should be focussing on for our future technology needs?
Laptops get the best press. They are common amongst students and often located on cows (computers on wheels) in schools. Banks of laptops remain connected and charge as they wait to move from class to class.
iPads are growing in popularity. iPad 2 gave us two cameras, but still no usb connection. The apps are getting better and more broad in their outloook and these computers are lighter, cheaper and easy to use. Training for teachers is improving and the ipad is proving to be a worthwhile prospect for mobile technology in education.
But my award goes to the mobile phone. That ubiquitous computer which has become progressively smaller, lighter and so multipurpose, most of us forget that in addition to being a game player, music player, camera, gps, calendar, email exchanger link to the internet and text messager, it can also be used as a phone! It's major drawback is the fact that there are so many about. In fact, too many brands on too many platforms with too many different options all requiring slight tweakings of the software code so the same application can run across different platforms. Yep, this is a problem, but not a terminal one. Let's face it, nearly everyone has a mobile phone these days, so instead of trying to discourage their presence in the classroom, why not get a supplier on the line, come up with a great bulk deal and mobile up your school? I'm sure the students will be keen to upgrade.
