I know many more than 4 people that access SASS from their pc's and phones. Maybe you better look into upgrading your devices or something!! I'm no computer expert, in fact I'm probably worse at it than you are but I really think you're blaming the wrong people!
I have noticed that since I updated my I-Mac and starting using Google Chrome I have to sign in to SASS but on my phone I don't. Oh well...good luck!!
