I''ll start off giving a bit of background on my smartphone usage.  I''ve pretty much been a Droid user for my whole life.  I''m definitely a power user and I greatly enjoyed having a keyboard.  I could type long text messages or emails with ease, and I never really had that much interest in switching to a non-keyboard phone.  Unfortunately, that decision was taken out of my hands somewhat.  I have the Droid 4 which I greatly enjoy, but it has it''s own problems.  After having it for about a year it got a pretty nasty crack on it.  I played around with some friends GS3''s and was very impressed with them.  However the rumors about the GS 4 coming out had already started so I decided to hold off.  I''m glad that I did, but a lot of my review will be based off of not having the GS3 and making such a drastic switch.  As I put in the title, it seems to be minor improvements upon a design they''ve found worked as opposed to the drastic changes previously seen.  Without further ado...The Looks:There isn''t much positive to be said about the aesthetics of the Galaxy S4 body to be honest.  It looks and feels like a cheap toy.  It feels... clammy might be the best way to describe it.  It really isn''t the best feel when you''re holding it, and compared to the HTC One it''s disappointing.  It doesn''t seem like it had that much effort put into changing it.  It does feel sturdy though, despite being a very thin phone.  I was able to get a good grip on it though which is important to me since I''m rather small.  Overall I would give the looks a 2.5/5The Hardware:Huge upgrade over.. well anything but a computer.  This really is just a small computer, and it runs flawlessly.  The screen is massive and great.  Easily the best one that I''ve seen on a phone.  The 5" screen could be a little bit big for some people I think, but for most of the younger generation will be ok with it though.  The battery is incredible as well.  My Droid 4 would die around 4 or so after a normal days use (streaming music, internet, tons of emails, etc).  This will last me all day, including going out at night which is a massive incentive to me.  The camera is great on it as well, much better than any other Android phone.  It is still slightly edged out by the iPhone though.  Overall though I would give it a 5/5 on hardwareThe Software:I''ll start with the obvious, it''s actually running the latest version of Jelly Bean, and should keep up better than other phones do (minus Nexus 4.)  This is a huge bonus, because Android''s because fault is that the OS is so fragmented.  Now, Samsung has put a ton of their own software on top of Jelly Bean.  The best description would be that it''s overwhelming probably.  There are a lot of Samsung apps that really will just never be used.  So I''m not even going to bother going over the party trick type apps.  Instead I''ll talk about a few that really caught my attention.S Health:  Helpful now, will be awesome in the future.  The premise is that it''s a basically a fitbit built into your phone.  It helps you track calories, steps walked, workouts, etc.  It works great now, but I don''t think that it will get better with accessories.WatchON:  Basically it acts as a universal TV remote and a Netflix browser.  It''s great, and I don''t even watch very much TV.  I suspect that this will become the standard soon, but until then this is the best version you can get.Air View/Gesture:  A great idea, but not great in practice.  It''s glitchy currently and doesn''t always work (or does work in ways that you don''t want it to.)Camera Software:  There''s actually a lot of really great features that come with the camera.  The most novel of them is the ability to take a picture from the front and back cameras at the same time.  I can see this actually becoming standard in the future as well.Overall I think that the software is good, but not perfect.  Overall I would still rather just have stock jelly bean.  Samsung adds some good features, but it also adds a lot of stuff that I really don''t need and can''t get rid of.Final Impressions:It''s a good phone, there''s no doubt about that. It''s not a great phone though.  The screen is amazing, the body isn''t.  The software is good, the hardware is out of this world.  It all comes down to personal preference between this and the HTC One I think.  Personally I''m fine just putting a case on my GS 4, but I''ve always been more interested in battery and hardware.  I can completely understand picking a slight downgrade on those areas though in return for a great body like the HTC One has.4/5
