This may be a very preliminary assessment, and my opinion will no doubt change as I test the phone down the line, but from what I saw from the unveiling, the Samsung Galaxy S4 will be the dominant phone in the coming year.
The Galaxy S3 came on like a storm last year and severely dented Apple's market share. This year, even with a new iPhone likely coming in the fall, expect the Galaxy S4 to become the dominant phone in the overall market, due to Samsung's continuing innovation where Apple tends to lag.
As many people have said lately, iPhones are for teenagers and old ladies, and any person serious about having a top-level phone will look right past the Apple aisle and head to Android -- specifically the GS4 (or perhaps the new HTC One, which is almost as impressive). Blackberry is attempting a comeback, but you can pretty much count them out in this fight. They've fallen too far for a couple new phones to get them back in the hunt, even if those phones turn out to be half-decent. Half-decent isn't good enough these days with superfast behemoths like the GS4 around.
So what's all the hype about with the GS4.
Well, you get:
-- Android 4.2.2 Jelly Bean
-- 5 inch screen
-- eight-core processor (translation: super fast)
-- Improve battery life
-- 13 Megapixel rear camera
-- 64 GB of internal memory and support for 64 GB more via SD card
-- Cool new features like eye scroll and floating hand scroll
-- Dual screen view
And a lot more
Samsung is innovating at a level no other phone maker is right now, and that is why they will soon find that the GS4 is the dominant phone in the overall market. There are those who remain loyal to Apple or other brands, but Samsung has done well in part because of its immense marketing budget, which makes it hard to not hear about their new products. Nobody, not even Apple, is as ubiquitous as they are in the world of advertising.
I fully recognize that Samsung's competitors will step up their games on new releases later this year. They have to in order to compete with this type of rock star phone.
But Samsung has a head start, and the team with the head start usually wins.
