I think a 1:1 initiative is great for schools that can afford it. There are many hidden costs in rolling out a 1:1 in a school aside from just the mobile devices. The wireless network needs to be updated which can be a very costly. Another costly expense is software licensing and security upgrades. Every professional development class I have taken has been less than helpful. If a teacher does not know how to properly implement devices in the classroom, the initiative will not work. It is simply not enough to hand a teacher a device and trust they can make it happen. They need to be trained and given tools to use in the classroom. This takes time and money. Also, some teachers are reluctant to change. Getting teachers to buy-in to the initiative can be a daunting task.
