An application from Omni Group for the iPhone shows amazing promise (LINK via the Apple Core LINK). It's a task list that not only will sync to your desktop via .Mac (take THAT BlackBerry) but also has location aware lists! So, if you're near a grocery store, for example, it will create a list of items relevant to that location (and THAT BlackBerry).
RIM's stock was juiced by the success of the BlackBerry Pearl (one of which I just bought, but that's another story). Will the Pearl prove to be a one shot success in the consumer market, much like the RAZR for Motorola? I'd seriously consider a short of RIM stock . . .
