I'm the defacto tech support for my church/neighborhood. I've installed Ubuntu on quite a few of these users, especially ones whose older machine was running XP, and they did not have the recovery disks to restore from, and the machine was crufted with malware such that it would take more time than it was worth to clean the system. In the first case, I gave them a 3-way ultimatum, spend $75/hr for at least 3-4 hours for me to clean the system, OR I would backup their docs, nuke XP from orbit, install Ubuntu, and life goes on OR they buy a new system with Win7/8 on it.. After seeing a LiveCD demo of Ubuntu, and my explaining to them that they would not be plagued with the endless malware and its slow down of the machine on Linux, they smartly opted for the "nuke/pave" option. Since then, word of mouth has spread and I've done quite a few more systems in the neighborhood. Quite a few of these were essentially unneeded upgrades, in that the user was not seeing any real slowness on the system due to malware, they just wanted their machine to perform better than it was under XP. These original "upgrades" were done using Ubuntu 10.04LTS as they were done in the 2010-2011 timeframe. Since the turd that is Unity/Ubuntu 12.04 (and above) I've switched to Debian Mint for these upgrades, as the "focus group" I tried on Ubuntu 12.04LTS with Unity were unanamous with their scorn for Unity. What with XP patches/"support" coming to stop in April, I figure with a little local advertisement on the imminent un-support for XP, I'll get a nice uptick in business doing these upgrades.. Mayhaps even enough work to hire some help...
