You don't need a laptop, however it is nice to have one. For now, it would be just as good to have printed out notes so you can write on them during class. I know that in Histo, Neuro, Lower Extremity, and Physio you will have to write/draw in extra stuff during lectures in your Powerpoint handout. So, that is why I would stick to printing out colored powerpoint handouts and have them professionally bound in the printshop. On the other hand, if you can get yourself one of those laptops where you can write on them like a notebook that would be excellent.
I professionally bind my notes in color (printing with my own printer using ink refill kits). After each class is completed I just file my lecture notes in a bookshelf.
I do not know what the school is planning for you guys next year. I heard that laptops or preprinted notes were thought about. However, we didn't get a labtop/ PDA/ or preprinted notes.
