So I just got the Galaxy S2 from AT&T today and coming from an Infuse 4G, I was somewhat surprised by the difference in quality between the two devices. Since I still have both phones, I did a side by side comparison with the brightness turned all the way up and auto-brightness turned off. It wasn't even close. The Infuse was much, much brighter and the colors were much more vivid. The 4.5" screen is nicer IMO than the 4.3" screen as well. I also prefer the chrome buttons on the Infuse over the cheap plastic buttons on the S2. The placement of the power/sleep button on the Infuse also seems more comfortably placed. So, really why would I want the S2 over the Infuse other than for speed and a slightly better camera? I guess I don't so the S2 is going back.
