wow, what a scientific test! using a different Browser in a different OS! but sure! its the processor thats the main difference! (for example, the iphoneOS is the most bloated POS I have ever seen and I wouldn't be surprised if full XP was faster...).
so whats the conclusion? Intel make a processor thats faster than the fastest ARM? yeah, they've been doing that for a while, its called an i7... was there any info given on ENERGY EFFICIENCY as that is all that really matters in the mobile space. not to mention that the A8 isn't the fastest processor that ARM make anyway...
and look, I hate Apple more than anyone, but stop thinking this is Intel vs Apple and voting down anyone who suggests that Intel isn't awesome, its Intel vs ARM, and ARM has been doing this A LOT longer than intel! and if intel do muscle their way in on this, they will force everyone to use their bloated x86 instruction sets, and then we as developers will have to worry about compatibility between two competing instruction sets.
