Well, I can't really tell what it should because i'm little aware of all 
the possibilities provided by the linux OS.

I'm a not a specialist in any OS. However, i'm a daily user of all the 
main operating systems Mac, Windows and Linux.

As a kernel developer I have only developed the device driver for 
Windows 7 and now i'm writing it to Linux.
