Galaxy S is a beautiful, sleek phone. It comes with really comfortable earphones and I think 8G internal storage, which according to someone I know is not nearly as much as an iPhone.
Anyway, pros of the Galaxy;
- Has free WiFi connection
- Can use your 3G network to provide internet connection to another device
- Syncs with GMail and Youtube automatically, I think this is inbuilt
- Larger screen than iPhone, thinner than iPhone I think
- Does not lag, you can flick through pages very quickly (picture your laptop doing exactly what you want it to do when you want it done, such a beautiful feeling)
- Free Samsung Apps, you get about 20 then it goes up to 30 and so on, from News to Sports to Entertainment, Health etc
- I really like that you don't have to remove the battery/turn it off to change the SIM
- And obviously there's space for a memory card
- etc (because I am yet to fully discover the phone)
Cons;
- It get's randomly slow moments, mostly happens when someone else is using it so it's easy to blame them but happened once or twice with me
- No illegal youtube videos available, youtube a song and 3/5 times you'll get mostly user covers, then again depends on the kind of stuff you search for
- Samsungs Apps cost me an extra 30 pounds on my monthly bill (to activate it you need to allow it to make calls, then it calls premium numbers

)
All in all, Samsung Galaxy S has it's pros but if you want a phone for downloading Apps then it might not be the best phone for you. Oh and the camera quality is ace but it is a Samsung ergo weak battery, have to charge it every night. And apparently you can make 3 way calls, haven't figured that one out yet.
