Windows 7 had this annoying Windows Update notification, but my four-person household at the time collectively only had 10 GB of 16 Mbit/s and given my former experiments with Knoppix, I knew that the UI of Linux was more configurable and less authoritarian and I assumed that I could learn more easily within Linux how to save on data usage (including the update process). Some people also told me that there would be no viruses on Linux due to its relative obscurity back then.
