You have already built a perception that, Linux is better, no matter what the reality in the real world.
Fact is that, when it comes to updates in Windows, I’ve never had to worry about them in my Windows 7 and Windows 8 machines, and didn’t really have any issues with XP machines.
For about 90% of computer users around the world, Windows is still the preferred OS, and it’s not because it’s what comes inside their purchases. People also have to upgrade from one version of Windows to another, and people still opt to upgrade to the next version of Windows, whatever it is.
Put a Linux machine next to a Windows machine in a computer store, and the Windows machine will always end up ahead, and be bought by the vast majority of consumers.
I have a dual-boot system in front of me, with Linux in a partition, and, try as I might, I can’t bring myself to boot into the Linux OS as often as I probably should. The reason being that, there really is no reason to do so.
Uh, again, no.
I use Fedora on one machine, specifically one with very old hardware, because Linux runs smoothly on it for the purposes I need it to (web, email, lightweight word processing) whereas WinXP no longer does. But it's only one of four "PC grade" computers I use; the others are a notebook with WinXP, a desktop with Win7, and an iMac with OS X (Lion). (Those are personal machines. I use WinXP Pro at work.)
Having used all of them, I can categorically state that the easiest machine to administer and keep up to date is the Fedora Linux box. The package manager handles everything behind the scenes for me, all I have to do is provide an admin password to approve updates. The Windows and Mac machines do the same, but only for a subset of applications.
I’m going to HAVE to dual partition, Linux and Win 7, because I have a project that must port well to linux.
