My comments on what these "training" (read brainwashing) slides say:
"Choice and Compatibility": Yeah, people use MS-compatible software because that's what comes with 99% of computers. It's not their "choice" at all. My Debian GNU/Linux system (I will from now on refer to this a "Linux", since that's what's familiar even if incorrect) comes with tons more software than my Vista system did, and it's quick and easy to add more, AND (with the exception of Publisher files) I have always been able to read files made on a Windows machine with MS software. Linux gives you more choice, and great file compatibility.
"Familiarity": Yeah, that works great until someone who's been using an XP box with Office 2003 gets a Win7 box with the new Office. Suddenly the menus are "gone", you have to make many more extra mouse clicks to accomplish the same tasks, and everything is moved around or missing in the "button-formerly-known-as-Start".
"Peace of Mind": Oh yeah. I'll give you a piece of my mind when I have to constantly worry about the next virus, worm, or spyware attack, or have to constantly strain my already overworked budget to renew licences and upgrade to the newest software because "the company" declares it so.
"Cameras, iPod, and MP3 compatibility": Never met a camera I can't access and automatically import images/movies from on Linux. Never had an iPod, so can't speak for that one. Almost any media player I've ever used on Linux can play MP3's.
"Printers and scanners compatibility": I've got a relatively new Canon printer (came out well after Vista was available). Vista used to be able to print to it. Now it can't. I can't explain why. Linux picked up on it right away without ever having to install a driver disk, and it's never had any problems. All of the scanners I own (both old and new) work great.
"Windows Live Essentials": What's that? From what I can see from the examples list the slides presents in parenthesis, I don't see anything that Linux software can't do.
"Games your customers want": I'm not a gamer, so doesn't apply to me. That said, again, people "want" it because it's what they've seen on Windows. I've actually seen some great looking games on Linux. If Linux was the dominant OS, I'm sure the games they "want" would be the ones they've seen on Linux. As for the WINE issue, I don't see what the problem is. You open your package manager (I use Synaptic), select Wine, hit apply, and it's instantly installed. From then on, to run a Windows program (if it's compatible with Wine), you simply run the installer just as you would from a Windows box, and it runs almost as if it were a native program. Yeah, for more compatibility you could tweak Wine or buy Cedega, or you could run Windows in a Virtual Machine or dual-boot. I just don't see the issue.
"Authorized Support": I've never used phone support, but every time my friends have, they've generally ended up more frustrated than before, because phone support has to go through idiotic "scripts-for-dummys" before you ever get to anything mildly productive (if you do at all). Most of them end up turning to friends or forums for help, which is exactly what you do on Linux. Plus, as others have said, there are "Authorized Support" venues for Linux as well, if you're willing to pay for it like you do on Windows.
"Video chat on all major IM networks": Can someone please tell me what video chat IM networks they're talking about? I can video chat with anyone I know from my Linux box.
"Word Click": I can't find any... Am I doing something wrong? All of the words I see only apply to why Linux is better than Windows! 😉
"Nothing is as complete as Windows 7": Most of the listed programs have Linux alternatives. Granted, Quicken is better than the Linux alternatives so far, and I've never used Zune, so can't speak to that one. But come on: Office 2007 -> OpenOffice. Photoshop -> GIMP/GIMPshop. iTunes -> Songbird, Rhythmbox, many others.
"Easy to Learn": Anyone who knows Windows can easily use the more recent distributions of Linux. And once they get to know Linux, it's a much more versatile, customizable experience! I can make my Linux system look and work like Windows, MacOS, or anything else. I can't make a Windows box look and work like anything but Windows. Yuck!
"Regular updates" and "Free downloads": Ok, they're comparing that to Linux? Linux can be as up-to-date as you choose, and updated as often as you want. And tell me what percentage of available software on Windows is a "free download" compared to Linux?
"Linux updates and upgrades are easy (marked as a myth)": Yes, they are incredibly easy. Let's compare. What I do on Linux: open Synaptic, click "Mark All Updates", then click "Apply". Done. All software throughout the system is up-to-date. On Windows: Go to a web site, download an updated installer, run it, reboot. Ok, one program down. Open a program, click "find updates" or similar, download/install, reboot. Ok, two programs down. How many programs do I have installed?!?!?! As for Ubuntu having "hundreds of updates a month"... first of all, this is a bad thing? second of all, that depends on which release you get. Since I use Debian, I'll use that as an example. There's Unstable, Testing, and Stable. On Stable, I get maybe one to five updates a week. On Testing, I get a few more. On Unstable I get many more. That's because of what their name implies. Except for the Stable version, the others are all in a state of constant change until they become stable. It's like giving someone a Beta-test version of software and saying it's bad because it's always being updated. Duh!
"Linux is easy to learn...": Installing it is easier than installing a store-bought version of Windows (not the "restore disk") when you consider that actually getting the hardware drivers that (in many cases) on Linux are automatically installed or easily available in package managers is simple compared to the internet hunt you are facing with Windows. I know that one from experience!
"...help documentation is limited": Tell that to the insane number of 'man' (manual) pages installed on my system. Tell that to the insane number of very helpful forums available. In-program help in Gnome programs (Gnome = Debian's default desktop/GUI) is as helpful as Windows in-program help.
"...you can't learn one version and be sure you know them all": If you truly learn Linux, you will easily be able to navigate them all. If you don't, you probably won't face that situation often anyway.
Ok. I just refuted almost the entire thing. That said, use what works for you. I don't like Windows, I don't use any software that needs Windows, so I don't use Windows. So what? If MacOS works better for you, great! If Windows, then great! If Linux, then great! Don't go trashing what works for many because it doesn't work for you. Also, educate the customer in a fair and true way or let the customer educate themselves about what fits their needs instead of feeding them unfounded lies and preying on their ignorance. That's just WRONG!
