Android and Apps
The more I use the HTC Incredible, the more I like it. And the thing that really makes the Incredible, er, incredible is its operating system, Android.
Android, as I'm sure you must know by now, was developed by Google, and is open in a way that the system it is most commonly compared to, iPhone's iOS operating system, isn't. A consequence of this openness is that third-party Android applications can easily get to market in sharp contrast to Apple's rather random iPhone application approval process.
In passing, it's worth noting that both Android and iOS have a "kill switch" that allows the remote, global erasure of applications the companies deem unfit for their platforms. I dislike this concept as it could be abused by both the vendors and, quite feasibly, by hackers. To give Google its due, developers were told up-front about the existence and details of the kill switch while Apple has always been cagey and unclear on the topic. Google has actually used this facility once but they did so in a transparent manner and for a good reason for which they get brownie points.
