For tv series and HD movies I'd like to watch on my phone on long trips, there is the most under-appreciated feature on android phones(except nexus) people forget, USB OTG. Put all your HD movies in flash drives and plug it in when you want to start watching. It is whole lot easier than swapping a external sd card.
I disagree with most of your post, but I wanted to know what you mean by the above statement except for Nexus....what does that mean??
I wanted a S3 when it came out but passed & passed on it only because VZW only carried the 16GB model, too small for internal memory these days. Fast forward the S4 comes out and did the same thing, I passed on it too; then they suddenly offered pre-orders for an S4 with 32GB Bingo! I jumped on it. The problem is they offer memory on the low end side and want us to use the cloud which means more data usage $$$ for them; no thanks, don't use it. I shouldn't have to connect to a cloud for my stuff and what about when you are in airplane mode? So the things that attracted me to the S4 32GB was all of it's features AND the fact has a removable Battery, to which I bought the battery and combo charger from Samsung for half price as a reward for registering the phone with them, can't beat that price anywhere for the Genuine article AND I can very easily charge an extra battery outside of the phone itself.
The S4 allows you to move apps to the SD card and I have a extreme card and have no speed issues with it. For me this right now is the perfect phone because of the 32GB, Removable battery, SD card and chock full of the features I liked. I otherwise would not have purchased it if it didn't come with a removable battery or SD card. The only thing I was hoping for was 64GB internal and I know VZW is opposed to it, heck I would have purchased an S4 128GB if they made one, I don't mind the price so much, after all it's a one time charge unlike a monthly service bill, so you get over it real quick. The thing I like is Samsung has given us a choice and that is very important unlike Apple that doesn't. No I'm not knocking Apple plenty of my friends have them, and they all know, ALL Apple would need to do for their tablet for example that comes with a whooping 128GB internal would be to add a SD card and removable battery and I'd buy one in a New York minute as they say; that is how important I feel about it. I'm not going to have a $900 device?? and in a year or two the battery doesn't hold-up I have to mail it back to them and get a REFURB in exchange for it? NOT going to happen in this universe for me or should I say to me.
I love all I have been able to do with Android and I only hope Samsung and the Android Market place in general continues down this path, I like an open eco system.
I'm a hardware guy by nature and while I helped other out with their Apple & Andriod phones/tablets at work I never put down my own money for one because I didn't care mostly for the hardware it terms of removable options and thus the S4 became my first smartphone, that is how strongly I feel on the subject.
As they say I VOTED with my Wallet.
