Same or not

I think it's funny how phone manufacturers will make so many phones that look almost exactly alike but just have a few differences. I know part of it is that they make different phones for different cell phone carriers. Like my husband's phone is the HTC Evo, which he totally loves. But they also have a ton of similar phones like the Mozart, Trophy, and htc desire android phones that all do basically the same things from what I can tell. Though maybe they are different, I'm not sure. And my phone is a Samsung Intercept and it looks very similar to some of the other Samsung phones. I'm sure if I worked for them I could tell all the differences, but really to me a phone is pretty much a phone lol.
