I didn't get my laptop until I was mostly done with the whole note-taking phase of optometry school. A few of my classmates had laptops...a handful of those brought them to class occasionally...and no one ever brought it regularly.
Our powerpoint presentations were available online to print at school for free. Almost every instructor, if not every instructor, posted the updated file after class if we printed an older version beforehand.
I love having a laptop, but I still prefer studying from paper notes, and I like being able to write (actually writing, not typing) myself notes off to the side. That being said, I had a study habit of typing out my own study guides anyway, but I printed those out, and I always had lots of things handwritten in the margins by the time the exam rolled around. A lot of it just comes down to personal preference.
The #1 reason I went back to re-download ppts was to search for key words, which is one of the advantages outlined above.
