It's all well and good talking about different versions of hardware but most people first become aware of alternative OSs when they already own the hardware. If they already have a 'Windows machine' then they will be blocked from installing Linux or any other operating system and they aren't likely to buy into something they don't know about when they buy new hardware. I am a die hard Linux user but would never have become one had I not been able to run a kjve distro,and install it on my existing machine
In the future, you're going to get computers as prizes in breakfast cereals. You'll throw them out because your house will be littered with them.
