Mobile devices for school

I use my mobile device to look up words for spanish class, however they can get distracting. I use my phone soo much for school. I use it to read books, research topics, and to look up random facts for the class. Without my phone i would be a disaster because i use it so often and affectively. Plus i use it to keep me entertained during class therefore if i didnt have it i would probably not be able to make it through the day. i also use it to communicate with classmates on projects and all other aspects do with with group projects. Thats why my phone is such an optimal device for school!!
