Summary: The open nature of the Android platform allows handset manufacturers to customize the software for use on their handsets. As a result, the Android software can look and feel very different on different handsets.
Conclusion: We love Android and we adore Samsung's vibrant AMOLED displays. But we could do with a little less TouchWiz on top of Android: it slows down the phone and it creates confusing redundant functionality.
Pros: AMOLED display, very good camera., Wonderful AMOLED capacitive touch screen, solid build, feels good in the hand. Very good camera, good GPS and WiFi for fast data when 3G isn't available.
Cons: Too much TouchWiz on top of an already capable Android, occasionally sluggish., Sluggish at times, TouchWiz hinders more than it helps.
