When I got this phone, I initially liked it very much. It was fast and exciting, with lots of new features. I particularly liked the camera, and the music player that you could tell what mood you were in.
However, I then started to get more and more problems with it, mainly around excessive battery consumption for no apparent reason. After realising that My Galaxy S phones were becoming projects in their own right, I gave up on them altogether, and went to the "back to basics" Google Nexus range of Smart phones which take a different approach.
My feeling now is that Samsung pack too much into their phones, and that they're a rather cheap and tacky brand.
