I just picked up my SR on Thursday. This is my first android phone (though I do have 2 Honeycomb tablets) and I agonized between this and the OG SGS2. After fiddling with both at a store, the SR was my choice since I live in an LTE area and I could not discern any lag difference between the two. Maybe if I knew how to induce lag I would have seen it. The SR runs all of my media flawlessly.
I do wish the SR had the OG's battery cover, since it is textured and looks better.
I wish both had a real home button, but I guess apple is to blame for that in the US market.
It would make sense for both to get ICS, as so many OG models have sold, so LTE was my deciding factor.
