It was great until you had a disk shared between the large monitors at school and the tiny one you had at home. So long as all screens are the same sized and layed out the same it worked good. However any form of using two different computers and the whole thing started to fall apart. Throw in multiple monitors and it isn't possible to do this usefully.

It also only worked well when you only had a few files in any folder. If you have 100 files that are related in one folder and you can't find anything without sorting it alphabetically. Depending on how your brain organizes things this might not matter.
