Went to the Sprint last night, they had the Galaxy S2 in the back room, and let me play with
I am a big Android fan, having owned the Nexus-One...EVO 4G...EVO-3D ( for just two weeks )...Nexus-S 4G right now.
First impressions, the device is razor thin, and very light, I could not believe how thin it was, and the large screen was amazing, but the thinness was shocking and cool. But after a couple minutes with it, I think TouchWizz 4.0 is just ok, much prefer stock Android. And it did lag a little here and there. I keep reading how this phone is butter smooth always, and never once slows or gets choppy. BS, it did lag. Going between live wallpapers and adding some widgets I saw some lag, which I did not expect. But really wasn't that bad, but still I did not expect any chop at all.
The screen, is huge, and is very vibrant with great bright colors with deep blacks. I have the Nexus-S 4G so I am familiar with this style screen, I know the S2 is the next gen version. But the resolution is just not right for such a large screen, it does look pixelated, and a little blocky. I can see once the new phones come out this Fall with the new 1280x800 res screens, the S2 will look very dated, like a HDTV next to a normal TV.
Bottom line, I think the S2 is a great phone, but only for those with old phones that need an upgrade from two years ago, if you have a phone from the last year or so; EVO 4G, Nexus-S, there is no point to upgrade, just wait there are much better devices coming, and coming very soon.
My overall opinion is that, yes the S2 is cool, but it seems late to the party, and that it will be eclipsed by better devices very fast. Not next year, but in the next couple of months. Samsung should have brought this to the U.S. back in April like the international version, but now 5 months later, I just can't confidently purchase this device, with knowing what is coming so soon this Fall.
