In my household, we have four shared computers, two desktops and two laptops (I’m not including the three tablets). Three of the computers (one desktop and the two laptops run Xbuntu Linux. The other computer runs Microsoft Windows 7. I can say without a doubt the computers running Linux are the least maintenance. They’re very stable and extremely secure. I have spent hours, sometimes days, attempting to liberate the Windows 7 computer from viruses, spyware and malware. The only maintenace I perform on the Linux computers includes sfotware upgrades, initial launch housekeeping and occassional operating system reinstallation to restore the computer to “new” condition. By the way, the tablets all run Android, a Linux-based operating system. Linux just saves me an enormous amount of time and nearly as many headaches.
