"(1) has windows UI"
Could you clarify what is so special and necessary about the Windows UI. I find Explorer to be horribly slow for file management, especially whn they bloated it even more in Vista.
"(2) can run all software I want to use (either runs the same program or has an alternative)"
Most software has a decent alternative, unless you have learnt how to use a particular program very well, the alternatives are normally good. You could always try WINE too.
"(3) use setup.exe (.sh, .whatever) file for installation of additional software that do not depend on some third party (apt-get, yum) database and have all needed files included (.so files, .dll files) (can have some exceptions, like LinuxD3D, Lin.net, LinVBrun)"
There are .deb's etc. available to do that, but package management is much better than the horror of Windows' Add/Remove programs - a legacy of the time before modern internet when you installed programs from 20 floppies.
"(4) is compatible with majority of old software, written 15 years ago"
More programs written 15 years ago run on my GNU/Linux box than my Windows one. (All the GNU core utils for a start :P) and MS broke a lot of compatibility with Vista.
"(5) uses GUI (for most options) or registry (for obscure options) for configuration, instead of text files"
Text config files are much less cryptic than the registry IMO, they are also much easier to restore and share. There are GUIs available for most of the config, I've only had to touch Xorg.conf when Cedega broke it.
"(6) supports any currently made device that Windows supports (including a USB thermometer)"
Buy devices with open specifications or Open Source drivers. We aren't magicians, we need the specifications to make drivers.
"(7) is compatible with games"
There aren't many good GNU/Linux games, I'll admit but I play CS1.6 and Oblivion in WINE. But again, this is really a problem of basically saying I will use GNU/Linux if it is Windows.
"(8) is so better (faster, more stable) than windows that I do not mind reinstalling the OS."
The Freedom of using GNU/Linux is already well worth installing the OS for. It doesn't take long, nor is it binding, and you can try it out. It's well worth just being free from malware, etc. for a start.
But ultimately it's your choice, you don't have to use GNU/Linux, but if you don't want to use it, please don't make shallow excuses as to why you would.
