Glore2002, I applaude your enthusiasm, which has been obvious since you started posting here at LQ. You asked for opinions and here are mine:

Where are word and control panel?
|
Of course, Word does not exist in a traditional GNU/Linux system. However, most of the students are young and their minds fresh. I long ago learned that "kids" are highly adaptable. You can provide Word, through a virtual machine or WINE, or you can preinstall OOo, KWord, or Abiword. Just be honest --- other than the basics Abiword is no match for even Word 97. Of course, most people only need the basics (professionals need, demand, and expect much more). OOo Writer does not yet contain a draft/editing mode (called Normal View in Word), which will frustrate many people. KWord uses a frames approach, which is unfamiliar to most typical users unless they have dabbled with Publisher or FrameMaker.
By control panel most people will find that in KDE at least, the Control Center is what they seek. Xfce provides Settings. If necessary, change the menu name from Control Center or Settings to Control Panel. Then they will always find "the control panel."

Do I have to take care of dependencies?
|
The typical user hasn't a clue about dependencies. All they know is when a software package is installed and then fails to run as expected, that the software must be crap. They don't know what to do after the software fails to run --- deer in the headlights analogy. That's why most people choose the distro route rather than building a GNU/Linux system from scratch --- the distro maintainers test all dependencies and the user should never even think about the issue. If you have students asking about dependencies then find a different distro.

Is there something like Photoshop in this Linux?
|
I'm not a graphic artist, but browsing the web indicates the overwhelming opinion is no, not really. For basic raster image work there is GIMP (GTK) and Krita (KDE). For vector graphics there is Inkscape (GTK) and Karbon (KDE). For most people who want only to perform basic photograph touch up and cropping, the consensus opinion throughout the web is that GIMP and Krita will more than suffice. For professionals, the consensus opinion throughout the web is GIMP and Krita fall short of Photoshop. However, your target audience is students and teachers, not professional graphic artists.

Why do I have to use Slackware if Ubuntu is much easier?
|
As much as I prefer Slackware for myself, I would not recommend Slackware for typical users. Most typical users never have installed an operating system --- they buy computers with the OS preinstalled. (Most people who operate a car never perform maintenance on the car.) To discuss installing an operating system is a waste of time with the typical user. If your students are enrolled in a computer USAGE class, then the topic of installing an operating system should be discussed only superficially. If the students are enrolled in a more sophisticated class --- where they learn more of what is under the hood, then installing software is a valid topic.
Is Slackware easier to use than Ubuntu? Non sequitur. The only thing the typical user sees and understands is the desktop. Once Slackware or Ubuntu is properly configured to boot into X, then the question of being easier to use becomes empty. Most typical users understand desktop icons and system "start" menus. That is all most typical users will need and venture to discover.
Is Slackware easier to maintain than Ubuntu? Irrelevant to the typical user. The typical user only knows "point-and-click." You will enjoy no more success convincing a typical user to manually edit a configuration file than you will convincing a typical car owner to change the engine oil. When typical users want to install a new package, they will look for a point-and-click method to download and install the package. The stock Slackware provides no such graphical tool, but some third-party graphical tools exist. If you want to sell Slackware to your students and teachers, then you'll have to provide such graphical tools.
Please understand that I am not passing judgment on the typical computer user. I am only sharing my observations about the typical user and I have been using computers for more almost 30 years. During that period I have been amazed at how the typical user refuses to look under the hood. I am not about to change human nature and neither are you. Typical users simply are not interested in what is under the hood. They only want to know how to download a web page, audio file, or movie. Typical users never have heard about using templates and style tags in a word processor. All they know is the "B", "I," and "U" buttons for formatting. Many people still use the tab key to indent the first sentence of a paragraph.
Windows and Macs use mount points too. The mounting process is masked from most people, however. The typical user who uses GNU/Linux is not going to know about mount points either because that is all auto-configured in fstab or udev. If you are discussing mount points with typical users in a computer USAGE class, then you already have lost their attention. You should instead focus on why they can't find the C: drive.

Doubt: If I have a 2 HDs system How many primary partitions can I create? 4 or 8?
|
Each physical drive can be partitioned into only 4 primary partitions. One primary partition can be divided into logical partitions, however. For SCSI systems the limit is 15 partitions, for IDE the limit is 64 logical partitions.
But again, typical users will only get glassy-eyed if you discuss the subject with them.

There are many reasons why Linux is safer than win.

Windows can be made secure too. More energy is required, that's all. However, the inherent design of any 'nix operating system lends well to securing a system with less effort --- but an effort is required nonetheless.
Quote:
Installing a program needs administrative privileges.
|
Users can install programs in their $HOME directory. In a secure 'nix system, that is the only place users can and should install software. However, the package must be compiled with that in mind. Most are compiled to install in /usr or /usr/local.

Much cleaner web browsing (less porno adds and cookies)
|
Completely dependent upon the browser and filtering software. The end result might be true only because many people allow their Windows boxes to become infested with viruses which tend to hijack browsers and URLs.
The same thing could happen to GNU/Linux users too if they are careless. Several months ago there was a discussion here at LQ about a screen saver (web collage) that randomly grabbed images from the web. Out of curiosity I tested the screen saver and the very first image downloaded was p0rn.

Linux was really thought as a multiuser system
|
Indirectly yes. The Linux kernel is based upon the Unix model of operating systems, which was always a multi-user system. In the late 1960s when Unix was developed, hardware was expensive. A single mainframe served all users through dumb terminals. Therefore a multi-user design was necessary from the beginning. Because of that multi-user design, basic security was inherent in the model.
The desktop PC movement was different: creating a single user machine. Back in the 1980s when Microsoft, Apple, Commodore, Sinclair, Atari, etc. all started, there was nothing inherently wrong or incorrect with such an approach. The goal was to create an affordable machine for people to use in the office and at home. Indeed, part of the goal was to bring computers to the masses, which previously had always been controlled because of the cost of hardware. The single user design allowed people to configure their computers the way they wanted, not the way an IT administrator wanted. In several ways the single user design, despite being based upon proprietary software, created new freedoms and liberty.
When the single user model began the world wide web did not yet exist, most office managers did not think about networking, and almost no home users thought about networking. Modems and bulletin boards were the extend of any "networking" most people considered or experienced back then. Therefore the original design of the single user machine was reasonable. Only after the world wide web and general networking exploded did the single user design encounter challenges.
Additionally, nobody predicted script kiddies emerging or people who wrote damaging virus and Trojan horse software just for kicks. Generally, most people tend to presume the best in others, not the worst.
In perspective and with hindsight, neither design approach is wrong or bad. The goals were and are quite different.

Slackware is more stable than other Linux distributions. . .
|
Although I have found Slackware to be stable, and I use Slackware daily, I'd like to see actual hard data as evidence that any one particular distro is more stable than another. All I have ever read is subjective opinions.

Why do we need to learn Linux?
|
I realize you are on a mission to "sell" GNU/Linux to other teachers and students. Please do not exaggerate or develop a fan-boy mentality.
Be truthful.
I much prefer the philosophical arguments for adopting GNU/Linux, which basically reduces to one argument: the freedom to tinker. People remain free to contract with others to use proprietary code, but the freedom to tinker and study the source code is invaluable. Most people are not qualified or trained to understand the software source code, but many are, and therein lies protection for typical users. Typical proprietary software is infested with phone-home and user-control nonsense, which would be impossible to propagate if the source code was free to be studied.
The great advancements in human society occurred when information and knowledge was shared. The great regressions in human society occured when information and knowledge was restricted.
Other reasons to sell GNU/Linux:
* Improved job skills. Knowing more than one operating system produces a stronger skill set.
* Simple curiosity. Exploring new ways of doing things is part of human nature.
I would refrain from technical arguments when trying to introduce GNU/Linux to typical users. All they know is point-and-click. Therefore confine the arguments to those the typical user would appreciate --- which is usability. Typical users don't care about what is under the hood. For kids, if they can't figure out how to play music, watch videos, or surf the web, then they will not be interested. Ensure your GNU/Linux systems provide those basics and then they will be more than likely ready to explore other facets of the operating system.
