Another reason, and arguably a more logical one, for splitting a stock is to increase a stock's liquidity, which increases with the stock's number of outstanding shares. When stocks get into the hundreds of dollars per share, very large bid/ask spreads can result. A perfect example is Warren Buffett's Berkshire Hathaway (NYSE:BRK.A), which has never had a stock split. Its bid/ask spread can often be over $100, and as of November 2013, its class A shares were trading at just over $173,000 each.
