Items already modified from original presentation:
remove some of the introductory exposition
make many slides less wordy
remove unnecessary points/side notes and combine slides when possible
add points to address things that were confusing to students
highlight all commands in red so they are easier to identify
add a "recap" slide midway through the presentation
use the Dropbox metaphor throughout the presentation
reorder some slides
Possible improvements to consider:
Instead of (or in addition to) some of the slides, give students a heavily-annotated "script" with all of the commands so that they can follow along even if they get behind. (The script can also serve as a reminder later on when they forget what certain commands do.)
Add another workflow diagram, perhaps early in the presentation
More explanation on SSH, and more detailed instructions for setting up SSH
Add more detail to the "recipe"
Add transition slides to make it more clear where you are in the presentation, and perhaps name or number the exercises
