Put that phone away? Or can mobile phones be useful in class?

Mobile phones are very important to everyone it seems nowadays everyone seems to have one and cannot live without one. In class is that it will help students be more comfortable in accessing information via email as many phones now have internets so more work can be available through the internet and email and passing information back and forth especially when the computers are not working or if you have done the homework but don’t have it in paper you can send it via email. Also using mobile phones gives student that freedom that they can learn independently and learn via imagination rather than just boring facts and the teacher just going on and on maybe the lesson plan is to be accessed by mobile phone and then they do the work which the lesson demands. But mobile phones provide a distraction because there are so many features and apps in a mobile phone now that students will be distracted and there quality of work will not be great they will be on their music playing games and accessing social network like Facebook and Twitter and this will cause the teacher and then later on them grief because they won’t get the work done. Mobile phones have caused addiction and have proven health issues such as less sleep in the night, eye damage is all that worth it for using mobile phones and then using mobile phones in class? What i believe is that mobile phones should not be allwoed in class there are other ways tot eaching and learning (computers, books, pen and paper) which will improve students writing reading and research skills when they have to if we have it to easy for ourselves that will mean that we are not really learning and when things get tough we wont get tougher but very weak because we will not get out of our comfort zones.
