I've been thinking about asking students to have devices like iphones instead of laptops or tablets. To me, it seems the greatest value is in access to information. I'd be willing to forgo the production benefits of the larger devices if I could also forgo the cost, infrastructure, and support that they require.
I look with a bit of envy at those countries that skipped the land line infrastructure and went straight to wireless. I'm amazed by the pace of technological progress and all the different ways people use their phones today. I don't like to bet on the future, but it seems to me that we are 3-5 years away from smart phones being able to almost completely replace laptops anyway.
What do you think?
