Growl + Prowl = Win
Its worth it just for email notification alone. My Gmail is now basicaly a push email service. Ive turned my fetch settings to manual now so Ill also save battery power. And it gives you a message preview so you dont have to close an app just to find out you got an unimportant email. Im using Growl for Windows and Prowl and have had no issues. Just buy it already.
