Samsung is a name brand. They sell phones, TVs, laptops, ssd's, HDD's, dishawshers, refrigerators, microwaves, tablets, and the list goes on and on. hTc sells phones. Of coarse Samsung's income and budget out strips most other corporations but it doesn't make them the best in any way, shape, or form. People know the name so they buy because they think of the quality associated. hTc just needs to get their name out there because I have both phones and in my personal opinion, the One is a better phone. Also, I wouldn't be surprised if Samsung in the near future buys a HUGE stake in Best Buy.
True story:
When I went to buy my S3 (Sprint) when it became available, I we to BB because they were giving me 120 bucks for my S2 as a trade in. I thought cool, let's do this! The BB guy went to get the phone and I started taking out my SD card out of the S2. Another BB guy said that was standing there said "make sure you don't lose that because the S3 doesn't have a micro SD slot to put it in." I looked at him with a blank stare just as the BB guy with the S3 walked up and re-stated what he said. "Yeah, the S3 doesn't have an SD slot." "you know, you have to put a screen protector on or you might scratch the screen making it unusable." I didn't say a word. After the BB guy activated the phone and everything was done, I took the S3's back cover off, took my SD card and slid it in the slot till it went "click" and turned the phone on to let it boot while I replaced the back cover. They both looked at me like I was a contagion about to infect the Eastern seaboard. I smiled and walked out.
