Perhaps surprisingly to some people, Linux hardware support 
  has improved to the point that everything worked perfectly 
  out of the box, just like on a Mac.

I installed the latest version of Ubuntu on my Dell Laptop. After a few minutes, I heard some strange noise from the Hard Drive. I googled to see what's going wrong and I found out that Ubuntu have some problems with Hard Drive Power management. The risks are damaging my SATA drive.

Unless you are using something supported by your Hardware provider, I really doubt Ubuntu will make it work out of the box, just like on a Mac
