if i were you, id just buy one for school and get a desktop for home. when youre walking around school and going back and forth, you dont want the crazy heavy shit that handles everything weighing you down.
honestly, what do you need a laptop for school other than to take notes? are you utilizing some type of photoediting programs, etc? If thats the case, then I can understand, but most of the time, people just need a laptop that opens up MS Word and Excel, and they are pretty much good to go.
