The case thing is an assumption, unless you are talking about certain individuals. Not everyone uses cases. I don't, as it doesn't guarantee protection of the screen from shattering, unless you want to add a big bulky case. Which negates some of the lower weight (which I see a lot of people mentioning) if you are doing so with the S4.
Also, the S4 beats One in terms of daytime shooting, but not at night. I haven't seen video/microphone comparison, though.
Internal specs of CPU/Memory for S4 might be higher, but in terms of actual usage is it faster? Like noticeably faster in terms of running apps? If not, I wouldn't say it "crushes" the HTC One. I haven't noticed any lag on my One. I think quad core with Jellybean or higher (Project Butter is what made the difference) has made Android pretty smooth on any quad core Android smartphone. Talking about how good the S4 is specs wise - unless you are running some high end apps - is like comparing the i5 to the i7 or 8GB DDR3 to 16GB DDR3 if all you are doing on a desktop is web browsing. Is 1.9 GHz vs 1.7 GHz making a huge difference when you probably aren't truly multitasking video apps and games? I don't know, maybe that's just me.
The S4 does have a bigger screen, but get this: I don't actually want a bigger screen. The One is actually pushing it for me at 4.7", as any higher and it's a stretch (literally) to use it one-handed. I don't want a phablet. I think 4.3 - 4.5" is probably ideal, and 4.7" is acceptable, but I don't want 5" or higher. If you like the S4's size, that's fine, but it's not the ideal screen size for me.
If you want the greatest specs, go ahead, get the S4. Personally, I'm not competing to have the best paper specifications. And one feature you did mention - the speakers - is far more important to me than .2 GHz advantage or eye scrolling or whatever else is unique to the Galaxy S4. If that's what matters to you, that's fine. I understand chasing specs. But if you are "Not sure why anyone would get the HTC One" you must not be reading any of the reviews comparing the two phones, or reading what people are posting in this thread. There are plenty of reasons to get either phone over the other. Or even the Nexus 4, or Xperia ZL.
I paid $200 with contract for my 32GB HTC One. I'm very happy with it. I'm getting a S4 for my brother when it comes to Verizon, but I doubt I'll regret buying the One even after playing with the S4.
It's most certainly an assumption but it's still accurate. I'd say overall 75% of the people I've seen out there with smart phones have cases on them.
For me, it depends on the materials...
Glass? It gets a case ASAP. iPhone 4, Nexus 4, LG Optimus G.
Aluminum? It gets a case. iPhone 5 and HTC One.
Plastic? Nope. Galaxy S II.
Kevlar? Nope. Numerous Motorola phones.
Nothing is ever guaranteed but it doesn't mean you shouldn't use a case if you feel the benefit of using one outweighs the risk.
TPU cases are more protective than most of those other "feel good" looking fluff cases. If buying a case, I make sure it's TPU.
If all what one will do on a phone is browse, then one does not need to waste time looking at a One or Galaxy S4. Get the One S or Galaxy S III/IV Mini equivalent or less. No need for top end fluff since there's little difference.
i5 to i7 is a big difference for me...Dual core with HT vs Quadcore with HT?
8GB vs 16GB? Not so much...
The S4 may have the bigger screen but are the dimensions still almost the same?
In other words, is the One's 4.7" screen with massive bezels or the S4's 5" screen with little to no bezels the same size comparatively? Which is bigger and which is smaller?
Or are you automatically assuming that because the S4 has a bigger screen, it's a bigger phone than the HTC One?
Those reviews talk about the build quality of the HTC One and front facing speakers...That's it.
I have little interest in "build quality" or "design" since it's aluminum and I'll probably end up putting a case on it anyway like I described above.
Sense and TouchWiz? I don't care about any of their features or gimmicks because at the end of the day, I will root it and either install a custom ROM to get rid of the Sense/TouchWiz or freeze their bloatware. Most of those Samsung gimmicks won't work with custom ROMs anyway and I don't care for it.
If I'm paying the same $200 price, then I want the phone with the most features I can use(read: not gimmicks), performance, and will last me for at least 2 years.
Two ways to extend phone life:
1.) Android updates by the manufacturer. HTC doesn't have the resources to compete on this aspect. Their 2012 flagship phone has now essentially been shitcanned and won't see the next Android update if the rumors are true which they probably are.
2.) Custom ROM scene. This remains to be seen, but if history is any indication, Samsung(the non-Exynos versions at least) will be ahead here.
Galaxy S4 is more likely to have more custom ROM support and see much quicker Android updates than HTC can ever hope to deliver.
It's being mentioned that HTC has abandoned their flagship from last year and won't see KLP and will stop at Android 4.2.2...Meanwhile, my Samsung flagship from 2011 will get Android 4.2.2
HTC could come next year and say KLP is the only Android update the HTC One will ever receive. I don't want to get burned by that.
I've been spoilt by "Nexus" pricing. I will never spend more than $400-450 on a phone ever again as long as this "Nexus" program still exists.
Oh, and I no longer do carrier contracts.
Now that I think of it, arguing over these two phones which I know I won't ever get seems a bit silly.
I'm not getting either phones, but if you held a shotgun to my head telling me to decide, it would be the Galaxy S4 no question.
