you may find some drivers don't work out of box, or very hard to make them working, like sound, adobe-flash, or even Chinese Font, or printer drivers, and sleep mode etc.
but once it's working, the system itself is rock solid, you don't have to worry about virus etc (still need to be careful not install unknown plugins though).
