I went down to my loacal AT&T store to test drive a Galaxy S II in anticipation of possibly switching if I don't like what Apple rolls out this afternoon. I have been hanging on to a 3GS for over two years now, so I'm itching to get a new phone and am not real excited about the prospect of getting a 4S (could be completely wrong, will know in a couple hours). Here are a few of my takeaway's after test driving the Galaxy S II: The Good: Beautiful 4.3" AMOLED display. I know it doesn't have the PPI of the current iPhone 4, but I literally could not tell a difference. The colors are very striking and vibrant, which is all the more enhanced on a 4.3" display. I have literally NEVER used an Android device before, even to mess around. Test driving the Galaxy S II today was literally my first time to do so. I've got to say that the Android OS was not bad. It was pretty intuitive IMHO, and I easily figured out how to get to most everything I needed to in a short amount of time. It was as light as a feather! I literally could not believe how light that thing was. I'm guessing a lot of it has to do with the rear attachment. It is a piece of plastic, whereas the iPhone is a piece of glass. That said, I did not mind the plastic at all, and I liked the texture it had as it would seem to be resistant to scratches and such. The Bad: The keyboard is freaking awful! I could not type worth a darn on that thing, and that was with a much larger screen and real estate to work with. I figure I would obviously get more used to it over time, but I've gotta say, I was really turned off by the keyboard. Fluidity, or lack thereof. You get used to how smoothe the iPhone operates when pinching and zooming, flipping from one screen to the next, scrolling down pages, etc. Althought not terrible, the Galaxy S II, and probably to a greater extent the Android OS, does not match the iPhone in fluidity. They don't have pinch and zoom, but some weird way of holding your fingers on the screen, and using the gyroscope to zoom in and out. Not terrible, but I much prefer pinch and zoom. Flipping from one screen to the next was not as crisp and reactive to that on an iPhone, and scrolling down web pages seemed to be an all or nothing proposition. That is, you scroll very very slowly, or you scroll down at the speed of light. Not much in between. Overall I think the phone was very nice. I think I would be happy with it if I were to pick one up. That said, I'm really hoping I don't have to go that direction as I am happy overall with iOS and the comfortability I have with it. That said, I'm just flat out not going to upgrade to a new iPhone if it still retains a 3.5" display with upgraded internals. As noted above, the presentation is in a few hours, so hopefully I won't be disappointed. That said, I thought I would post my Galaxy S II impressions for anyone else that might have had similar thoughts of looking elsewhere if today's presentation misses the mark.
