I think a split would motivate speculators currently mentally deterred from the idea that this virtual thing is "so expensive". They'd rather own 60 coins than 0.6 of a coin.

Here's this virtual coin that a low level speculator can't even buy a full instance of. That has to put off a few people.

To achieve similar effect, some people are proposing changing the default unit to mBTC, uBTC, or satoshi. While it is not splitting, it should have similar effect. Instead of saying they own 0.6 BTC, they'll say they own 600 mBTC.

This is what I had in mind. Interesting to note that it's getting suggested already.
