So I've been a devout dropbox user since it came out a few years ago but i've been amazingly frustrated with the amount of free space and the limited control. Sugar sync has much more control, more free space, and even sycs with iPhones and android phones! Until today when I tried SugarSync. You get 5 gigs by default plus an extra 600mb for learning the features and then you'll get another 500mb if you sign up through someone's referral link! Then when you refer people, each bonus is 500mb. This all adds up fast! https://www.sugarsync.com/ I'm definitely not going back to dropbox! that is 6.6 gigs of free online synced cloud storage without even having to refer anyone yourself! Test it out and let me know what you guys think! I think this is definitely a dropbox killer. Update: you can store files in the cloud without them syncing as well. Just upload to the "Web Archive" in the file manager! This is the best part for macbook airs with minimal storage!
