I guess you can sleep peacefully now. We already have enough of such BS across the internet. The best thing you guys are doing is making Samsung (aka GS2) a popular name.
BTW, you seem like a guy who just reads the headlines and ignores to read the full content. Did you just grab this statistics from a random AT review?
These are basically browser javascript performance statistics. SOftware and hardware are both involved. Irrespective of numbers, I doubt anything is "smoother" compared to GS2 in browsing.
