I could care less what chip it has in it. It will make very little practical difference. What will be a difference is how much faster the data is on this phone in an LTE market. 12 to 15 or more mbps down! Yes, that is as fast as some home internet speeds! I doubt I will care about an Exynos or OMAP or Qualcomm processors when I am streaming as fast as wifi or using Tango to see my kids at live speed anywhere not just hooked up to wifi! (provided I get to keep my unlimited data) lol!
Battery Life will be more important to me than the processor.
Bring on the Skyrocket!
I have an Atrix 2 with a OMAP dual core and had the SGSII with a Exynos dual core which I returned because I live in DFW and suspected a Samsung LTE was coming in November. The Atrix 2 got a 2500 on Quadrant and the SGSII had a 3500. In terms of practical use and "snappiness" I could not really tell a difference or a slight edge to the SGSII, not enough to keep you up at night. Most Reviews says the the Atrix 2 say it is plenty snappy enough and the UI is very fluid. Do not get wrapped around the axle before you even see the phone for yourself...I would take slightly less paper performance for a better battery life!
