Just installed the sync tool on my windows as well and it's not heavy plus the sync settings i mentioned on my MAC, automatically worked on windows too (sync specific folders & files). Not sure if ODFB works the same way, but for me one of the reasons we are thinking between O365 SP onlive vs box and leaning towards box is the sync tools for all platforms, (When i tried preview of ODFB on our MAC, it crashed both on Yosemite and El Captian), plus of course the unlimited storage.
