I would feel that using technology in the classroom is of great advantages given the advances in technology.   The greatest tools will be collaboration tools such as forums, blogs and wikis which will enable the students to cooperate with each other and with the teachers.   There will be far more interactions between the teachers and students and between the students themselves.   But I feel that there is a limit to technology in the classroom as there is a need to maintain the personal space of the students and teachers.   There should not be so much interactions that it affect the personal lives of the students and teachers concerned.
