Most I have are just launchers for Crackberry, Buzzd, Reuters. Even though myspace isn't fully compatible with the 8700g trackwheel... I still use it as it's easy enough to just email back & forth with people via that when I'm not in front of a pc. Plus obviously I have facebook.
Also I have Viigo on there as well for newsletters. Since I like my drinks.. I have Mobile Bartender on there as well.
