Well, it's still early days as far as education and computers go. There are some amazing resources out there though. For example, my kids regularly use Khan Academy. For some reason, the way he explains things just clicks with them.
For anything Khan doesn't cover, Wolfram Alpha is an unbelievable tool.
For writing, some kids are going to do better on a text editor or word processor. I know I can no longer sit down with a pen and an empty page and just write.
I'm glad to see schools trying new things though. You could take a teacher from 150 years ago and drop them into a classroom and they would be able to work as a teacher. There aren't too many professions where that's true and it seems like we should be able to do better.
One thing that is working well for my kids is reversed classrooms. Rather than get a lesson in class then homework problems, they are expected to learn the material for homework and the teacher helps kids with problems during class. It doesn't work for every kid though and our one-size-fits-all approach fails too many kids.
