TVOPDX  I like the idea of this. And it does put my MacBook Pro to sleep faster and nicer than the system itself. However, I find that my battery only operating time is cut in half. When I check my energy saver settings, it's always set to custom. When I force it to Better Energy Savings, it shifts to custom without any action on my part. As a consequence, the three plus hours I used to get with careful energy management has dropped to a measly 60-90 minutes. SmartSleep has a ways to go before it will work for me.
