One interesting observation from the new HTC Radar and Titan is that HTC have been able to move their add-on "apps" such as Sound Enhancer, custom camera options and Attentive Phone to Settings--that is these will no longer be apps to download but instead will be baked in the OS directly.

That's a good move for HTC as it seemed kind of silly to have separate apps for those--who wouldn't want those options? It also signals that HTC is able to inch a little closer in modifying the OS. It will certainly be interesting to see what other OEMs do with this ability.
