The ability to work from anywhere is great, especially when using Google Docs for inputting data into documents! It's easy enough that we can have students complete their own reports without assistance if they are willing/able.
I wish there were more options of what could be uploaded or downloaded (such as drawings). There isn't much in terms of training materials available online which makes it difficult at times but not impossible -- just takes some searching around with trial & error until you find something useful. Some of our teachers aren’t familiar w/Google Drive so having all information stored together was helpful during class time while also being able to share files later.
