For a person who's used both phones, I find your mark up rather one sided. Naming several points on the Iphone side, while showing a meager list on the galaxy S side.
Your first two plus points are very opinionated personal statements. Point two might be debatable, point one isn't. the overall superior smart phone experience? C'mon, you don't use those sort of biased lines in a comparison..
Point three. The the android market is a bit smaller. However it has over 200.000 apps in it. Apple sits around 400.000. Basically when you have a good app on the android market, you'll have a copy on in the apple store, and vice versa. There are more android users, so basing this on demand and supply, the android store will eventually outgrow the apple store.
Bigger doesn't mean better. When you have 200.000 apps available, you'll have a few gems surrounded by ****. The same is true for 400.000 on the otherside.
Point four. The iphone has a higher resolution, yes. But the screen is also 15%~ smaller. This is going to be hard to show on a youtube video, but take a look at this one.

The samsung screen is brighter, the colors are more vibrant and if you compare the small print. You see that the characters are readable. In the Iphones defence, it's an LCD screen and they don't perform as well at tilting angles. I would really advice you to go to a local electronics store and just watch both screens. The extra pixels which the Iphone offer are best used while reading a book/website. Pixel wise, you won't notice a difference while watching movies. The Galaxy S has better colors and viewing angle though, which is something you do tend to notice. The reason you don't notice the difference in pixels that much, when you're watching a movie, is due too movement and the relative small screen. If you pause, and look up close, the Iphone does have the best quality, No argument there. This is really a personal preference though. personally, I'd go for the iphone in the screen department, mostly because the vibrant colors really do their magic in a comparison. Alone, both phones produce amazing quality images, and I'd rather have the higher resolution, compared to more vivid colors.
Point five. Very clear recording on 720p, at 30 frames a second,
-just like the Galaxy S-.
Galaxy S offers more functionality and higher quality pictures, while the Iphone has a flasher. On a side note, This is the first camera that can be called decent on a Iphone though!
Quality wise, the Galaxy S takes the best shots. When it's getting dark, the Iphone over takes it. When it actually is night, both cameras are crap. Still, when you come home late at night and might be slightly intoxicated, the led flasher is amazing!
Cons you might have missed are less supported formats. on the Iphone, h.264, Mpeg 4 while the Galaxy S supports - Divx 3, DivX 4, DivX 5, DivX 6, h.263, h.264, mkv, wmv, xvid
Only bluetooth 2.3 on the Iphone, Galaxy S uses Bluetooth 3.0. Iphone also loses in the battery department, and lacks a slot for an SD card.
The Iphone does have superior built quality in my opinion though. They both can take a hit, but the Iphone feels more robust. The plastic kinda makes it feel cheap.
When it comes to intergration. If you us apple products, go for the Iphone, no doubt. Everything syncs, it's amazing. If you're a windows user, I would advice Android. Mostly because it's more open to windows products and ofcourse anything related to google(All hail our future overlords, google.).
[Anti apple]A plus on the Galaxy S department also might be that samsung doesn't track your every day movement like apple does. [/anti apple]
