Technology is a great tool to use in the classroom, but it is always important to consider the time demands that new technologies have. If a technology takes a long time to use, then you are spending less time teaching the content of your lesson.
For example, using google spreadsheets is a very useful tool for collecting data from multiple classes, but it takes some time to teach students how to use the tool. It might not be beneficial to teach google spreadsheets to a third grade class because it will take a long time to teach most third graders how to use the technology. It would probably be a better idea to use google spreadsheets in a middle school science classroom as the students have generally spent more time with a computer by this age. It is important to know your students and their abilities.
If it is going to take too much time, it could be better to use old-fashioned methods. However, if it doesn't take away from the content or take too much time, technology should be used in the classroom. Educators needs to make a decision, giving thoughts to the benefits and time demands, about whether each technology piece should be used in their lessons.
