My take on it is this:
If you have to have a removable battery and/or sd slot, OR you take all of your pictures in well lit areas, the S4 is awesome. How about the S4 is awesome anyway? It is a great device.
I come from a background of tons of phones, however I've had the most Samsungs. Go back to the Omnia, and that's the first WP smartphone I owned. Samsung has always made a good phone whether or not it was for you is a different story. Even before the Omnia I had a flip phone they made. I don't count the flip phone though, as it's a different class of device.
Every Samsung device I've owned I've liked. They're not bad. Also, they're not amazing. All of the things Samsung touts as "innovative" I've never used. Smart stay, for example, is a resounding no among most people. They pack in as much as they can that most will never care about. They're cool selling points and after the sale is made those features are nonsensical. As far as I'm concerned, that's ok. At least they're trying stupid features that may possibly catch on.
Smart scroll? No I have a thumb for that. I want the page to scroll when I want it to scroll. I also have no desire to wave my hands around the device as if I'm performing an act of magic. If I'm reading a book on my phone, which I really wouldn't ever do, I don't care if one of my digits has to touch the screen in order to turn the page. If anyone around me sees me waving my arms in the air they may think there is a swarm of locusts coming or something and be alarmed!
All joking aside, we all know a lot of the features they offer won't get used. It's not that they're bad or don't work. Without people like these, we'll never get anywhere technologically. Someone has to implement features we won't use in order for us to see that we won't use them. That's an important space whether or not we would like to see it or not. Samsung does a great job with each phone they bring out, silly features or not.
I, personally, chose my HTC One for the photo highlights. I'm a father with a very young daughter. The highlights are a big deal to me. It's a means for me to share cool stuff with our family without me having to edit things or really do anything at all. I chose my phone based on one feature alone, and I'm happy with my decision. Just because I chose the HTC One does NOT mean the S4 is a bad device. I would never EVER say that. The camera is nice, internals are solid and it doesn't look stupid. S4 is a great phone. I miss my Note 2 every day because Samsung makes such a quality product.
Please guys, please quit the stupid flaming. They're all good phones these days. The S4 is second to none based on YOUR NEEDS. The HTC One is second to none based on mine. You really can't compare both of them on the same level, you just can't. They offer different things that people are looking for, and that's the BEST OUTCOME! Everyone gets to win!
These threads need to go. There is no better right now, only different. It's a fantastic time to be an Android user. Everything we want is right here, we just have to make the right choice in the carrier store!
Here's a better alternative to these type of threads:
I'm going to buy a new phone, I need x, y and z features. Which phone is right for me?
This avoids all the bashing, comparisons and general silliness.
Food for thought:
The guy at work sitting next to me with his S4 and me with my HTC One have never tried to compare phones. We just show each other cool apps and pictures and move along. Why do we continue to have this conversation here in forums full of smartphone experts? Each of us is a smartphone expert, start acting like one.
