I am currently an iPhone user...but I am hardly an Apple fanboy. Well, fangirl. I did buy a 3GS at launch and like it. But, I did not upgrade at every launch and in fact was using the 3GS up until this last Sunday. A family member switched phones and passed down their 4S to me so I am now "updated" to a 4S. Likewise, the only reason I have an iPad 2 is that a family member gifted it to me when they bought a new one. My feelings about Apple and iPhones? I think they are nice hardware. I think the ecosystem works for them. I don't 100% *hate* the walled garden approach and there are a lot of great apps out there. But the point at which I do *hate* the walled garden approach is in regard to file support. This is usually more in play on the iPad rather than iPhone though since I don't do much doc editing on the iPhone. I do *strongly dislike* iTunes though...but I use it on a PC, not a mac. As you can tell by my having the 3GS for 4 years I'm not a hardcore fan who must always have the latest and greatest. And though I like the hardware, I find the whole "iPhone & iPad" hysteria over-hyped. So, that all out of the way...I'm considering taking advantage of the current AT&T "smartphone trade-in" promotion to trade-in the 3GS (and likely keep the 4S as a backup...or sell the 4S later) towards one of the android options. With a 2 yr contract renewal this means I'll only pay $99 for either one? I have picked up both the HTC One and Samsung Galaxy S4 in the AT&T store this week and as much as you can hold them with the theft removal cable attached, I think both felt fine in the hand. The screen on both looked pretty good to me (again, though, coming from a 3GS and 4S). I understand the HTC has 32gb storage but no expandable SD slots? While the "cheapest" S4 is a 16gb model but to which you can add a microSD card? I've survived on a 16gb model phone for quite a while...I keep only my favorite music with me...but additional space would be nice. I briefly considered the S4 because of the user replaceable battery...but then realized by 3GS battery is 4 yrs old and I've never had a problem. In terms of all the apps & widgets and navigation...I found both to be slightly overwhelming in store...but that is probably in part because people play with them so much that they get overloaded and I couldn't figure out how to remove items from the screens? I realize there will be a learning curve obviously. That said...anyone know of any youtube "android phone tips for dummies" videos? I guess I get the feeling that either one would be fine for me since it would be my first android phone...so, any tips on how to make the choice? Other things to consider? Also, I believe I correctly searched and found that both the One and the S4 use microSIM cards? So this means I could swap the sim back and forth from either one to the iPhone 4S if I desired, right? Thanks to anyone who made it through my excessive *brain-dump*. This was a bit longer than I planned.
