I don't have any technical objections to it, but there is value to having a consistent experience across the platform. Right now, the difference probably is not that great between Sense and stock, but I'm sure HTC sees Sense as a competitive differentiator, and there-in lies the danger. I'm sure it will be tempting to keep tweaking it, until at some point you could hardly tell the phone was an Android device, and non-HTC apps looked wildly out of place. If I have any misconceptions please correct them, this is just my take from reading what information there is out there on it, I don't have a Sense device.
