Google's chief accepted gear but no pay as Apple board member

After the Google IPO he never took any salary with the intention of making money. Anyways why would he do it? After all he's on #59 (4.4b net worth) on the richest Americans list. (http://www.forbes.com/lists/2008/54/400list08_Eric-Schmidt_O...).

is this the 3rd time or the 4th time now?
