As a heads up the thoughts I typed below are what I feel about the two flagship phones from Samsung and HTC, if you feel differently please share, but let's keep it civil.
[COLOR=#red]Y'all know how hard I went for the SGSII and SGSIII...and deservedly so because those two phones could be considered game changers. But honestly and truthfully I must say that even with the drawbacks of having a non-user replaceable battery and no Micro-SD storage capabilities I feel that the HTC One is the better phone overall this time around. I'm not saying it's better than the SGSIV by a longshot, it's pretty close actually. I still feel you can't go wrong with either one, but at least for me if I were going to purchase either of the two, I'd DEFINITELY go for the HTC One...here's why in no particular order:
The Super LCD screen while not as "colorful" as the SAMOLED screens that it gives a more realistic representation of colors AND it's better when used outside.
The features introduced in the SGSIV are indeed innovative...but I don't see myself using them.
Usually I don't care about cameras too much, but I like HTC's philosophy of upgrading the camera sensor to allow more light in...although it lacks in megapixels (4MP) the low light and motion imagery is superb on the HTC One.
I can't believe I'm saying this but I'm digging the aluminum unibody (aesthetically) of the HTC One...much more than the body of the SGSIV. Notice I didn't say BUILD QUALITY...because actually the high impact polycarbonate shell of the SGSIV is quite durable and damage resistant...as much so or even moreso that the aluminum on the HTC One (just think you damage the back on the SGSIV just buy a new battery cover...no such luck on the HTC One, you'll just have dents, scratches and gouges on the aluminum back).
Even though the SGSIV is a new phone and different than the SGSIII it still has the been there done that effect since I'm coming from having the SGSIII for almost a year now. The HTC One will be a fresh new experience and actually when compared to its predecessor the HTC One X it's almost an entirely new experience.[/COLOR]
[COLOR=#red]Small things like front facing stereo speakers on the HTC One make a big difference, from the reviews the speakers sound excellent.
Again this is just my opinion...if you feel otherwise you are very much entitled to do so. I still feel like the SGSIV will sell better, but that takes in account the huge marketing advantage Samsung has over HTC.[/COLOR]
