It was the first Droid to be on the "Droid Does" site and was the best Android phone that Verizon had at the time. It had commercials all over the place.
Samsung (non-Nexus) runs Touchwiz, HTC runs Sense and Motorola runs Blur. Since those are the main cell phone manufacturers in the U.S., it sounds like all will be slow to receive updates based on your post.
Listen, I'm not going to get into all this with you. The droid incredible was not a flagship, it was overshadowed by the Droid X (which had all the commercials). The droid incredible 2 was not popular either. I knew it wouldn't get updated when I bought it, I guess you didn't and that sucks. I don't have it anymore and don't care if it ever gets updated again.
