I think all the responses you have received so far are right on target. No one can make you a believer. It's up to you to give Linux a far try while keeping an open mind.
Nevertheless, I decided to share how I got to be a committed Linux user.
In the early 2000s, I heard about this Linux here thing. I told myself that, if I ever got a free computer, I would give it a try. At the time, I was working for a company that manufactured high-end security software for a QNX, Windows 95, and Windows NT/2000 domain environment doing software training and tech support.
A couple of years later, one of my co-workers was closing up a side business he had of buying surplus computers for $5.00 each from the university where his wife worked and reloading them to be "grandparent" computers--basic Windows boxes that could be used for email and websurfing and simple word processing. He gave me two left-over IBM PC 300 (original Pentium 300 MHz boxes).
By a series of happenstances, I ended up loading Slackware 10.0 on them and learned my way around Slackware (which, by the way, rocks). Then I met a guy who told me how he was running a website from his den using Linux, the LAMP stack, and no-ip.com
.) So I set up a website because I could. It worked. I had fun. (I gave the other box to my daughter in Georgia.)
I found lots of support on-line in the Slackware newsgroups and here at LQ.
Two years later, I worked up the nerve to port my personal laptop (Dell Inspiron something or other--6000 I think) over to Slackware. I've never looked back.
Now, the only reason I have a Windows computer is that sometimes I have assignments in which customers want the results in some MS Office format and I'm still a novice at WINE.
Linux does everything I need or want to do with a computer, without nagware, without constant registration fees, without worrying about viruses or intrusions. It's easy to configure and use and gives me flexibility--such as a choice of desktops (Fluxbox is mine)--that Windows does not. Plus it's faster by every benchmark.
(Yes, I run an AV and a firewall, because I consider that to be simply part of safe HEX, but I don't obsess about them as I used to and I don't feel as if I have to run lots of security stuff in the background all the time everyday and do regularly weekly scans for adware and spyware.)
Linux prints to my network printer, runs my file server, streams videos across my home network, allows easy updating (usually without reboots), and, as a bonus, gives me ssh and scp.
Also, if I break it, it's a darn sight easier to fix than Windows.
If the Windows registry gets hosed, you're done. End of story.
If a Linux text configuration file gets hosed, boot to a live CD, edit the text file, and, most of the time, you're back in business.
Linux is also easier to use once you understand it. But it is different from Windows, so there was a learning curve. I had spent almost 20 years becoming very good at DOS and then Windows 3.1, 95/98, 4.0, and 2000/XP (including administering Windows NT/2000 domain controllers, though not the domains themselves).
We were all newbies once.
