distraction free computing. your computer did 1 thing at a time. your attention was focused on that one single task to the exclusion of everything else. no interruptions, no distractions of emails, messages, web.

your computer was secure, it was connected to nothing but a few peripherals. now it's constantly connected to an insecure network that is looking for new and clever ways to find your identity to steal, your credit card information to sell and abuse.
