Interesting, I didn't know Windows 8 has many features, but I don't think I can consider install Windows 8 in a Pentium 4 3.0 GHz with 3 GB RAM.

You should not consider ANY old OS, really ever. Outside of learning what support used to look like, which is effectively worthless, conceptually using an old OS is a bad idea. Windows 8, especially, is only one generation newer than Windows 7 which is already crazy old. Windows 8 is something like eleven versions old already!

So the disadvantage to choose LINUX is based on the drivers for different devices that you will use

That's incorrect. Linux has much broader driver support than Windows, and both have much broader support than MacOS. Support for more hardware is actually a huge benefit to Linux. That's why Linux and BSD are available on more platforms than any other OS.
