[General Topics] DarqAnshin:
Personally, I'm disappointed with HTC. I don't walk around with multiple batteries but I do use the microsd card in my EVO3d all the time. In fact I probably use it more than anything else when I want to work off of a document and don't have wireless. I simply pop it into my Transformer and go to work.

Here is my thought, wait for some benchmarks to come out. I know that I am leaning toward the S4 even though I am disappointed in it. Here is why.

Battery life: (Winner Samsung)

HTC has let me down on many cases with the EVO, EVO4g, EVO3d. Even after romming the devices the battery life still is pretty subpar compared to many of the phones. For me the fact that I can swap the battery or get a larger battery is kind of important for me.

Wireless Charging: (Winner Samsung)

Even though Samsung is being a little b*tch and selling it as an accessory, it still is an option. With the HTC One's case you can't do wireless charging which honestly is a very nice feature to have.

Looks: (Winner HTC One)

Samsung dropped the ball on this one in my opinion. Using Kevlar, changing the shape slightly (making it thinner doesn't count IMO), getting rid of the button all of that could have been a step towards the right direction. The HTC one is sex on a stick for me. I've had iPhones, and to me the S4 is like the iphone 5 now... kind of bland

Expandable Memory: (Winner Samsung)

Samsung got this right. I love being able to swap my sd card out or save an entire days work to an SD card and archive it if I have to, Instead of swapping out music or having to have a wireless connection to get my music I can just drop 40gigs worth on an SD card and I'm good to go for a few days. It makes it great for those metro commutes, plane trips, etc. I know both offer onboard memory which is more than enough, but there is something to be said with having a few different cards for work / music / interchangeable devices. For myself, I have 3 sd cards that I've swap in rotation between my transformer and my phone and computers.

Rooting / Unlock (Winner: to be seen but leaning towards Samsung)

Rooting and roming HTC isn't that difficult, but compared to Samsung it is a beast. I didn't realize how easy it was till one of my friends got an S3 and showed me. Hell three other guys in my office jumped from Motorola Droids or HTC because that one S3.

UI: (Personal choice)

The Sense 5.... its ok, but for me it was ok. TouchWiz.. again its ok. I end up pretty much using my own launcher and widgets. With that said, I have been using Sense almost entirely from day one. The widgets are great, but Samsung does have a few nice features with their UI that makes me look and go "Now that is spiffy"

Screen: (TBD, but for now HTC)

Until I get my hands on an S4 I'll compare the HTC one from the store to the S3. IMO The one wins hands down, especially outside in sunlight.

Camera: (TBD, but for now HTC)

I'm not a big camera person.. If it takes a picture and I can use it for notes later I'm happy. My girlfriend usually goes ape sh*t over the cameras though. You would think these things were DSLRs that she could make phone calls from. From what I have seen HTC wins with the camera, but it looks like Samsung could tie it up with the features. As far as I'm concerned (until I touch the S4) the HTC One will always win in this aspect only because features can always be software added to a ROM.

Upgrade Support: (Eh...mixed bag)

Samsung has been pretty good about upgrades. HTC use to be good but their past few lines take a while for it to get the latest OS builds. Mostly because of the Sense UI. Personally, I looked at XDA and saw better support for the Samsung than the HTC in terms of support overall. I could be mistaken. Take it for what you will. I expect both to get the latest Android version and then from there.... well new phones will be released to make them forget about these phones.

What I am interested in seeing is the Motorola X phone in June. I may just hold off till then... if I can.
