Well written as an article, but many weak points. It kind of read like the same type of self-assuring cheerleading piece that Mac, Amiga, C64, and Linux users used to have to resort to in the face of the Microsoft juggernaut. Shows how much things have turned around in just the last five years or so (well, for Mac & Linux anyway).
First, 1 & 2 have nothing to do with Windows itself. The same can be said for building a Hackintosh or Linux machine. My OSX HP Probook was $550, and my Linux Mint i7 / 8GB / dual-view tower came to about $1200 including two 23" LED monitors.
-3. Software Library
Somewhat valid and yet still weak at the same time. How many different word processors, databases, or spreadsheets does any one person use? As for variation of type, I have never gone looking for anything for Windows, OSX, or Linux equally, and not found it. Including some pretty far-fetched ideas that I was sure I would have to write myself.
"lots of browser choice" - most of which started on Linux. "experience competing ecosystems" - every OS has emulaters and virtual machines. [rest of paragraph] - all of which you can do, sometimes better and/or easier on other systems too. The only thing I ever missed after leaving Windows was DeLorme's Street Atlas.
-4. Software Backwards Compatibility
Again, largely true and largely myth. Lots of things break as an OS advances including Windows. Programs broke from 95 to 98 to ME. After I got my first XP machine about 1/10 of my software had to be replaced (not updated) when SP2 came out. The second paragraph is just propaganda. And DOS / 95 / 98 programs no longer ran right or at all under ME / XP onward. On Linux most things are recompiled as the kernel changes.
-5. Oh, come on! I don't even have to say anything.
-6. True. Although, again, you're stretching it with the backward compatability thing.
-7. Not true. You can install anything on Linux and Gatekeeper on OSX has three different settings including off. Again (see #5), the only validity to this point is if you're going to compare a desktop OS to one smart phone.
-8. For the same reasons as points #3 & #4, this is just not true. I personally have never, ever, one time, installed any mainstream Linux on any x86 PC and had it fail or not be able to use some component. As for OSX, yes you have to be more careful about what you buy, but it's not like there are whole classes of components you can't use. There will be high-end graphics cards that work, multi-track audio cards, high capacity HD's, etc. Also, OSX can support a lot of add-on hardware directly - some things don't even need a driver.
Aside from gaming (a definite), about 2/3 of this article could be titled "Pretty Decent Reasons To Keep Using Windows". But "Awesome"?, "Amazing"?, [insert eyeroll here]. Hey, I'm not putting down anyone's choice, whatever works - go for it. Just be real about it too.
