Opportunity for Palm
Well, Epocrates, the killer mobile app for health, has come out on webOS just a few weeks after the iPhone version. It has a couple of major advantages over its iPhone sibling:
1. Palm units have removable batteries - i.e. get an after-market "rump shaker" and you've got double the battery life. Just not an option with iPhone. Epocrates stores all its data locally so you dont have to worry about constant data traffic killing your battery either, just the screen and CPU
2. Because webOS has true multitasking, you can switch to another app like email and not have to wait for Epocrates to re-load a humungous medical database when you switch back.
Get in there, Palm!
