There are a lot of issues that MS has to deal with that make it "easier" to use and install "certain" software packages. Linux may have new and different ways of doing things that what people have done for years with MS desktops, but it does not mean that one is better than the other. Each has its good points and its bad points. Now with MS going the way with its desktop interface with Win 8, like Ubuntu did going from GNOME 2.x to Unity, there will be much to deal with then. For now, most people prefer Windows over Linux for its ease of use. Win 8 will change that opinion for many users.
So yes, the installer for MS Windows would be much better if it was broken down to installer file and language/help pack files, like Linux is currently doing.
NO, Windows is not better than Linux and Linux is not better than Windows, as it currently stands. We all have our own opinions which is the better one, but it does not need to be discusses on this list.
The real issue is the way LO treats the different platforms with one not needing language packs while the other one does. That should not be. It should be the same with all the platforms, download the installer file and download the language and help packs that are needed beyond the basic English ones in the install file. If you do it for Linux and Mac, you should do the same for Windows. It is only fair, is it not?
Also, with the reworking of parts of LO so it would work properly with Unity, the developers will/may need to do the same with Win 8's tablet style of interface on their Win 8 desktops and laptops. Some articles are stating that people may move over to Linux [with not Unity style of desktop environment] once Win 8 comes out. So we will need to help these Windows users with their needs, and not rant and rave about how bad Windows is/was. We need to help them move over to LO from MSO and help anyone who moved from Windows to Linux with their issues and needs with dealing with LO in the Linux desktop environments.
I use Ubuntu for my desktop since early 2010. I still use Windows for some systems though. I like the way Linux has everything you may need for software packages without needing to pay all that blood-money for doing your needed work. They should charge for their work, but not prices that seen to be made to suck as much blood-money as possible from its users. Now Linux has issues with drivers for the most up-to-date devices, since volunteers have to buy the devices and write the drivers for them, instead of the device developers writing one for Linux. Although there are other issues that make Linux not the best for many users, it is still a vital platform of many. Each has its good and bad issues. Neither it a "perfect" platform. So let us stop the "my platform is better than yours" issues here. It is hard enough for LO users to get the Windows people to use a free package like LO over paying for MSO on their Windows systems. There is where we need to target Windows users, not their use of Windows over Linux platforms. We need to get users to switch to LO, not try to convince them to switch to Linux. This is the real need. This is what we need to keep our energies focused on. LO is free and is just as good, or better, than MSO. We need to prove it to its users.
