New hardware needed

[LP]

The kernel of MacOS on the other hand is based on (Free)BSD, another open source operating system ...

As far as I recall, Mac OS was initially proprietary project where Steve Jobs along with some other guys participated. Later, they've based Mac OS X on some portions of BSD in their NeXTSTEP, but correct me if I'm wrong, it still remains proprietary, isn't it?

But why has Windows this huge market share? Because if one buys a computer Windows is pre-installed. So if Dell, HP and all others would install Linux, I think the market share of Windows would decrease rapidly.

"Why" is a much more complex issue. OEM distribution sure helps, but I bet there are historical reasons also. As a counter example, Asus tried to push Linux-based OS on their budget Eee PC line of netbooks, but many people formatted and reinstalled Windows there; now the entire Eee PC line uses mostly either Windows on Intel's platform and Android on ultra-portable line.

you are right, mac os x is a closed system. but many hackers use freebsd/linux drivers to allow hackintosh to run on any non-apple computer, mainly if one has amd processors.

"why" windows still is the king of the hill? 'cause the inmense software base, think about, if a designer can run photoshop on linux natively, he will switch out of doubts, same happens for any other kind of software, another reason many people didn't switch is because nothing can compete with microsoft office, even if you can use wine. linux, unfortunately has been related to geeks or rocket scientists and it is not windows. the ubuntu distro has made a good job on making linux easier for humans, but still not enough.

From Wikipedia:

Thanks to its permissive licensing terms, much of FreeBSD’s code base has become an integral part of other operating systems such as Apple's OS X that have subsequently been certified as UNIX-compliant and have formally received UNIX branding.

and

Other operating systems such as Linux and the RTOS VxWorks contain code that originated in FreeBSD. Debian, known primarily for using the Linux kernel, also maintains GNU/kFreeBSD, combining the GNU userspace and C library with the FreeBSD kernel.^[37] Darwin, the core of Apple OS X, borrows FreeBSD’s virtual file system, network stack, and components of its userspace. The OpenDarwin project (now defunct), a spin-off of Apple’s Darwin operating system, also included substantial FreeBSD code. Thanks to the permissive FreeBSD License, much of FreeBSD now also forms the basis of Apple OS X and OS X Server.

It's not the GUI part that's from BSD of course ...

Exactly, I wanted to mention this in the end that the software base creates a vicious circle. Granted, there is Microsoft Office for Mac among other alternatives that work on Linux too (e.g. OpenOffice, LibreOffice, GIMP, Autodesk Maya). I myself have spent some time working in LibreOffice on Mac, but unfortunately, it doesn't handle well Word 2007/2010 documents that have shapes, equations, custom formatting and other visual customizations.

This is unfortunate, as I personally think that Windows 8 Metro style similarly to its mobile variant are regressions in terms of visual interfaces, yet Windows users including partly myself will have to cope with this silliness.

Just to keep you updated, my new hardware works, Windows 7 is up and running, too. The specs changed a bit, it's now an AMD FX-6100 (6x3.3 GHz) and a Radeon HD 7770. Man it's fast! And silent. But no more time now, I've got the Orange Box and have to play Half-Life 2 (waiting for this since years ...)
Of course it was a bit more expensive ... but less than 500 €.

I'm glad you got yourself a new PC.
But I seriusly hope that this new machine won't draw you away from programing (by playing all the latest games) to much.
