Ok here's my average joe opinion. I just picked up an iPhone 4 and was looking at possibly returning it. But I have decided to keep it. Anyway, when I was at the Best Buy, I took a gander over the other phones. I saw the Samsung Galaxy S Vibrant for Bell and the Samsung Galaxy S Captivate for Rogers. I was told they were both the same phone. Now first off, I felt both phones were very nice. The Samsung screens were gorgeous, I would have to say even nicer than my iPhone 4. I was immediately taken back by the screen size and amazing contrast of colors. I was also told my iPhone 4 screen is supposed to be sharper. To be honest, just looking at the screens I couldn't really say that my screen was sharper. I did absolutely no research buying my iPhone 4, as I always assumed it was just the phone to get. The only reason I was even looking at these other phones was because of the possibility of me returning my iphone 4. Now with that being said, there is no way I would confuse any of these phones with a iPhone 3GS or my iPhone 4. And this is coming from me, a new iphone 4 owner. I will most likely buy the next iPhone, but I honestly can't say I will not consider something else, especially a phone with those amazing big screens. Again, this is just the average joe opinion, meaning I'm not a tech geek.
