I don't believe Linux will ever be a widespread used OS. CMV.

I am a huge computer geek. Id say I'm in your 98 percentile of PC users. I game, I do a lot of media work on computers, and I run a business via my computer. I also have a fair amount if experience with macs. Both OS are pretty user friendly and offer a lot of functionality. I've heard often how Linux is on the rise. I have a Linux tablet and frankly, I find it extremely hard to use. Being as technology literate as I am, and still having problems. The fact you have to use the terminal for half of the functions is crazy to me. I'm sure I'll get the hang of it, but I can't even imagine my technology illiterate family or friends picking up Linux. Change my mind, and show me how it'll get big.

EDIT: I think I need to clarify a few things. The first time I made this post, I was in the car on my phone, wanted to get the post out while it was fresh on my mind.
-I feel I need to clarify my linux experience. I used Ubuntu on my tablet for about 2 months. Honestly, I enjoyed my experience, though it certainly had a different feel than Windows/Mac. I had to use the terminal for a great deal of tasks, probably because I was using a 'non standard' processor (ARM7 instead of something like an Intel), so there was a ton of compatibility issues. With Mac and PCs, I could download a program, install via GUI, and if a compatibility issue arose it would alert and redirect me. With Ubuntu, I was running into needing to use the terminal to have to compile and install many applications. As I said, I only had 2 months with linux (my tablets digitizer busted, waiting on the part ATM to replace it); but I couldnt imagine someone like my mother having to  use the terminal

-I feel like my question needs to be retitled to "... used OS for personal and professional computing by an individual user". I understand many servers, security, networking, etc is based off unix, but I dont think my father will ever go to work and sitdown at his Linux computer and begin to put in data. I understand that he could, but I just dont see it getting that big.

-Those saying Android is Linux. Yes, I recognize and understand this. But in its current standing, its not really a plausible OS to do a lot of multifunctioning tasks, more high end stuff, etc. Dont get me wrong, I love android, huge fan boy in that regards. Have and android phone, 2 tablets, a rooted OUYA, and a few other devices. Its an amazing OS, but in terms of full blown personal computing, I just feel like its not there yet. It cant run flash/java items as properly as something like a mac or pc, android's internal task killers have cost me valuable data when 'minimizing an application', and multiviewing applications is nearly impossible. Something like Cornerstone could have fixed this, but that was squashed. As a college student, I need to be able to view two programs at once. Heck on my PC, most the time Im using all 3 monitors, 2 applications each. This is why I installed Ubuntu, was so that I could get some more functionality out of my android tablet. Note, it multiboots, and it has a keyboard.

Linux already is a widespread, mainstream OS in the form of Android. It's likely that this is how it will spread in the consumer space, since it provides all the basics of a modern OS without any licensing costs. 

Now that "desktop"--as a category--is quickly diminishing in favor of other form factors, Linux is likely to be the go-to OS for a broad range of experiments from phones, tablets, entertainment boxes (things hooked up to TVs), Occulus Rift-type platforms and others.

Although a bit disconnected from the user, Linux is also driving the majority of web applications with consumer front-ends, and thanks to the rise of virtualization may become yet more common in the form of "OS-in-a-box" to provide stable APIs that can run on a variety of hardware and devices.
