Comparison Samsung Galaxy S vs. iPhone 4

I had share these findings i have:
Design: Samsung Galaxy S is bigger with 4inch screen - iPhone4's 3.5 inch screen. However, Samsung has 480 x 800 pixel resolution while iPhone has 640 x 960. when put side by side, you could see that iPhone4 has a crisper screen resolution. As for design quality, iPhone4 is made like a glass composite materials which adds to its weight making it abit heavier than Samsung. Design win by iPhone4 cause it's mre pocket friendly n offers on hand ease of use.
User Interface: Galaxy S runs Android OS while iPhone4 has iOS 4.0. Both OS offers fluid scrolling n very responsive. Samsung Galaxy offers more customization. Different homescreens where u can put widgets to, similar to HTC.
Multimedia: iPhone4 is a better multimedia device. Screen resolution n built in iPod software has been unrivaled. Note that Galaxy offers DivX compatibility. So for those who fond of downloading DivX videos, they might lean towards Galaxy S more as they don't have to converting their videos.
Camera n Video Quality: it seems that iPhone4 has better image quality compared with Galaxy S but comes to video quality, your choice would have to depend on whether you want to have the option of setting video resolution to HD /VGA. Samsung Galaxy S has that option while iPhone 4 doesn't.
Web Browser, Connectivity: Now for web browser, both Safari n Android browser are two of the best web browsers on mobile phone. Both renders web pages very fast n scrolling is very smooth. Now the deal breaker is whether you want flash or not. Apple has forever closed its doors on Flash for iPhone while Galaxy S will have the option to do so in near future. Connectivity, both mobile phones supports WiFi b/g/n but Samsung added DLNA compatibility to Galaxy S. So if you have a WiFi equipped TV, you can easily stream media from phone to home TV. Both phones also have GPS but iPhone 4 has a lot of turn by turn navigation available on App store while Android mkt is lacking but Android has Google Navigation which is free, at least in the UK n US.
Games n Applications: iPhone 4 has the largest selection of mobile applications. Android, though it doesn't have an extensive collection but best part is most of apps are free on Android mkt.

You really wont lose in whatever phone you choose because developers are now making their most popular iPhone apps available for the Android market as well and if you can't find the exact same app on the Android market, there are plenty of free alternatives available.
