Not BS to the average user

"In conclusion, Apple's adverts are misleading. This is not a "Mac vs. PC" issue, but rather "Mac OS vs. Windows". Apple should have been forced to make this clear in their ads."

If you ask the average computer user what their PC runs the reply will be Windows and it's precisely those users that the adverts are aimed at. It's only, usually, the more techinical users that have an OS other than Windows installed such as Linux and the like.

Personally, I am able to differentiate between the various operating systems and understand that they are refering to Windows, so why can't others?
