3. are to afraid to experiment
Linux has much to offer, it can do many things, and it always working to provide you with better things. Linux does not need drivers for every piece of hardware, you don't have to reboot every time u install / uninstall something, you do not need 15 CD keys, you do not need $500 for the o/s and a few programs, you will not have to wait 20 minutes for programs to close, you will not have to worry about every thing you do giving u infections, and you will NEVER see messages like this:
