I don't understand. The fine print says you can only install on one computer. This means to use Sync I have to buy 2 licenses (otherwise you have nowhere to sync to). I have 4 computers, a Mybook, ipad and smartphone. How many licenses do I need? The price of a license seems reasonable to me if I only have to buy one but if I have to buy 7 then there are cheaper options (unfortunately without the Trust-no-One security). I have not researched this but my gut tells me the move away from folder secrets to certificates seems like a downgrade in security and possible compromise of TNO. patric
