Google has a policy not to split its stock. There are a couple of companies, and successfully so, that do the same. The point is that a stock-split is not really of any other purpose than splitting what is already out there in smaller pieces, so supposedly to get a more liquid stock. The stock then "looks" more affordable, but it really isn't.

At some point though, the stock price might so high that it's actually hindering people to buy it (since you have to buy at least ONE stock, investors normally buy pack of a 100)...
