Long time apple fan, I owned pretty much every single phone Apple has ever sold. I did not want to go to the iPhone 5, and I kept wanting to try something different. That ended up being an HTC One. Very enticing design, at least it was at first, but that excitement slowly went away. Used the phone religiously for about a month... I liked the screen size, but after a while, you realize that you need that screen size because the operating system is simply not as smooth as apple's OS. To me, even basic tasks such as clicking on links, opening and moving through emails, it wasn't as smooth as it is on an iPhone. I liked the notifications options, and the fact that I was able to customize everything, but in my opinion, most those things were easier done on an iPhone. My two biggest issues though - battery life, and the bulkiness of the device which made it such a pain to turn it on and start using. This thing went through battery FAST, and while I don't stream videos, I would consider myself a power user. The size would not be an issue if there was a way to turn the device on without hitting the power button on the top, try that with one hand while device is in a case, fail all the time! Over the weekend, one of my friends helped me get iOS 7 beta, on my old 4S, and now I am back and loving it. Notifications are now significantly better, and this is sooo smooth all around. I can go on and on about what makes it better, but I am sure most of you already know by now. In conclusion, grass is not really greener on the other side, we've had it so good with the iPhone, I think sometimes we forget how good it is! Not perfect, but definitely better than the HTVC one.
