How do you know my assumption is wrong? How do you know Linux is not weak? Just because it is not targeted as much as windows, does not mean it is not weak. Let's assume that everyone is using linux, home user's; desktop, laptops, netbooks, enterprises .. etc ... ; there are countless application written for linux like linux office, linux sql, linux blah blah blah. So with that being said, hardly anyone uses windows because it's not user friendly. So now, which os is going to get targeted? Windows or Linux? Where is the DDos going to come from?
