hiya bloubul, what don't you like about opensource? lack of support? some Linux distributions are very refined, putting together some of their own programs, and charge a small fee for professional long term support just as Microsoft does.

many varieties of Linux are no longer homebrew patchworks of geeky programs...instead they can provide a robust & cohesive operating system.

If anyone wants to checkout Linux, I usually recommend booting your computer with a live CD/DVD...Linux Mint 9 is probably the best for anyone thinking about trying to transition from Windows to Linux:

the mini-DVD above has the best default set of programs to browse websites, play music & videos and all, right out of the starting gates. here are other variations:

Burn a CD/DVD from the ISO file, and your computer can be booted into a live desktop to try, no need t install.

Also, install WINE, and many Windows programs will run, and can sometimes even run the SETUP.EXE installers. Very few Windows-based programs I care about...I enjoy using a fractal graphics program, surprised it works with all the complex calculations...likewise I use a program that generates tide prediction charts for when I want to go fishing.

Here are some useful links for trying to find Linux equivalents of some Windows-based programs:
