Are iPads in the Classroom Doing More Harm Than Good?

Aside from financial concerns, there is also concern that the tablets may be misused as more than just a learning tool. In another recent article, the same Los Angeles school system found that high school students were quickly and easily able to "hack" the district-installed security filter, allowing them to access banned websites such as Facebook and YouTube.
While the idea behind integrating technology into the educational process sounds good, the reality is that these tablets can do more harm than good. These tablets allow students to become distracted during class time and concentrating more so on the technology provided to them than the subject matter at hand and could therefore, hinder the learning process.
While some believe that the tablets offer a positive impact on teachers and students, there are still many parents and tax-payers that oppose tablets in school districts, saying that the large sum of money should be spent on other upgrades rather than iPads; more teachers, new school furniture, and updated computer labs were among the many improvements needed on the list.
Do you believe that tablets in the educational setting are doing more harm than good? Should the money spent on tablets be better spent elsewhere?
