Whats different: While Linux is not natively supported there is a work around. Can easily stream videos & music, does a real nice job with photo albums, can post to Facebook with a click. Also sharing is awesome! You can post public links (think Rapid Share) except others do not need an account nor are there download limits or wait times. You can share files & folders with and without passwords with others. Great to use in a small business environment! Web based file manipulation is also a nice bonus. Can email files in to be backed up. You also can get email reports to file and folder activity that is shared.
