I spend far too much time browsing the web, and I do often end up on linux-related sites. A fair number of sites are still dedicated to converting windows/osx users or helping new Linux users. In particular the latter aim is noble, of course.
At time it does get a bit tiring reading the comments sections though -- and that goes for both Linux advocates and their detractors.
Quotes collected from the web are given within "".
As an aside, most linux users, but perhaps not most windows and OSX users, are well aware of the difference between Learn-ability and Usability. A program may well be easy to LEARN how to use ('intuitive') but it may be a pain in the arse to actually USE. Most linux CLI tools require a bit of extra effort to learn, but once learned, are eminently usable.
0. Fewer than 1% use Linux or Ubuntu/Mint/X is the most popular distro
According to my blog, 55% of all visitors use linux (Win 40%, OSX 2%). This blog, given it's content has a positive bias towards Linux users.
According to my professional university homepage (I'm a chemist, not a Comp. Sci. person) about 11% use Linux, while 74% use Windows and 12% use OSX. My homepage, by virtue of being strictly related to my field of research, is biased towards users who are professional chemists.
So what to do?
For starters, what does 'use' mean? Do we only mean as a primary Desktop OS? Or do we include servers? Or even indirect use, such as visiting websites run on linux servers and using devices with embedded linux? These problems also apply to deciding which is the most popular distribution -- do we count embedded? Server installations? Or only Desktop usage?
The problem is compounded by the problem of measuring usage, regardless of definition. For commercial OS one might use the number of licenses sold as an indication, but that won't work for a Free OS. Same goes for number of downloads. Repo access sounds like a good idea, but in addition to most major universities (+ companies and kind individuals) running mirrors, a fair number of us use apt-cache to cut down on both our and server traffic. And what about people who, like me, have a large number of computers which they use each day (desktop at home for watching tv, laptop at home for work, desktop at work for...work, three desktops at work for number crunching, router at home with busybox/tomato)
There would of course also be the practical issue of compiling all the stats, so this approach isn't used today.
So...for OS share 'Net applications' statistics is often used, see discussion e.g. here. Website stat, however, do not adequately distinguish between Number of Users and Number of Visits. The selection of reporting sites also influences the results.
Still, the problem is even greater when it comes to crowning the reigning distro. Most of the time distrowatch data is quoted, and it really makes absolutely no sense. I use only linux, and I visit distrowatch less than once per year -- because why would I? I use Debian, I'm happy with Debian, and I have no longer any time to explore other distros without a bloody good reason, and even if I did, distrowatch wouldn't be the place I'd go looking for information. I really wish articles would stop quoting distrowatch data.
1. The year of the Linux Desktop/Focus on mobile devices
"That's why I feel it's more important to focus on how Linux performs in growth areas like mobile devices than on a desktop that's increasingly less relevant for content consumption."
This is, if not a meme, then at least a standing joke. However, there's still this idea that Linux NEEDS to become a big player on the desktop and that it has so far failed to achieve this. Alternative, Linux NEEDS to focus on mobile devices where they can grab a large market share.
Well, guess what -- for a lot of people every year is the year of the linux desktop -- we're using linux as our only, or primary, OS.
Also, there isn't a NEED for linux to become anything.
What most linux users feel is probably that rather than necessarily converting everyone to some flavour of linux, it would be nice of non-linux users would stop forcing proprietary formats on everyone.
At my current job people insist on emailing .docx files for some reason. This
1. more-or-less forces Windows users to upgrade their office versions (which is the real reason behind changing the file format)
2. pisses off anyone who isn't using office --- such as linux users. A guess-timate would be that 80% of the documents emailed contain so little formatting that a plain ascii file would have been enough. For the rest, pdf would work just fine since editing isn't required.
Really, you can use office if YOU want to, but don't 1. pretend that it's superior to latex because you can click on things or 2. force it on other people.
2. 'obscure' terminal commands
"Look it's 2009. The public doesn't want to type in commands. GUI's have been around for how long? It's obvious by the success of Windows that users want an easier experience."
They are only 'obscure' if you are dead-set against learning what they do. There is no difference between typing in a command and looking through a graphical menu. You still need to be willing to dedicate at least a modicum of effort towards learning.
And guess what? There's a reason why the terminal/command line/cli is still around. In fact there are several. For a starter, it's a faster, easier and more convenient method once you've made a bit of effort of learning how to use the standard *NIX tools such as gawk, sed, vim etc. Not everyone uses their computer for data processing, or even work, and that's fine -- some people live their lives in the browser and won't benefit much from using the terminal (but they really shouldn't complain about its existence either).
Also, the idea of 'getting rid of the terminal' as one sees sometimes show s a complete lack of understanding of how a linux system works. GNOME/KDE/Xmonad/XFCE/LXDE etc. are just shells, interfaces on top of the linux kernel. They are like thin sheets of ice covering a deep sea -- most of the action is to be found underneath.
And that's a GOOD thing -- in windows there's little reward for making the effort to learn new things. In Linux, you can learn as little or as much as you want -- you'll get rewarded for any effort to learn that you make.
3. 'Too much' choice
"Fragmentation: 1% of the market split into 100+ distros. Divided they fall."
In the beginning I fretted a lot about choosing the 'right' distro -- after all you don't want to waste your time learning something that's obsolete or not as useful as the next thing around. As it turns out, there's little difference between different distros.
Well, the differences are there there, but they are typically down to philosophy, package management or number of packages in the repos.
I feel more at home using apt-get/aptitude than yum, but since a fair number of users use a graphical package manager, this really doesn't matter much.
Other than that, most distros are the same, and are derived from four or five main distros (the Debian and Fedora/Red Hat families probably being the largest ones). So, instead of 100+ distros you have 3-4 distros which are really not that different.
The differences between windows 2000 through Windows 7 are larger than the differences between any of the linux distros.
4. No drivers/hardware support
"The real killer with linux is using peripherals. Drivers suck if they exist at all."
To date I've only had one piece of hardware which didn't work immediately -- my Diamond ATI Wonder HD 750 USB TV card. And I blame ATI for that, not 'linux'.
5. No games means Linux sucks
"I gave Linux a shot. Despite the irritating little problems I encountered I tried. And then my nephew wanted to play a game and it became all too clear--Linux has no chance."
This is true. But are we discussing a system for casual gaming or are we talking about a computer OS? I'd hate to write articles or do modelling on XBOX or Playstation. If gaming is what you are after, then by all means, find a system where you can do it. Whether a publisher releases a game for a particular platform has little to do with the superiority of that platform and all to do with market share.
Anyway, people can use what they want -- what irks me is when they pretend they'd use Linux if only...and then some half-baked, poorly informed 'reason' is presented.
Use or Do Not Use -- but make no excuses.
