That that camera module has some serious optics and associated hardware. Also that it is tied to a proper xenon flash and a proper dual led video light as well. Because if it is then I'm in.
Sony has given its Xperia Android smartphones range a boost with the Arc S, it’s fastest model yet featuring a 1.4GHz CPU. Sony Ericsson Xperia Arc S The Xperia Arc S remains in keeping with the sleek styling of the rest of the range and includes an 8.1Mp camera with 3D/2D sweep panorama functions, 720p video and HDMI …
1.4Ghz is more than 1.2Ghz whether its dual core or not.
With a dual core, you don't just double the clock speed to get the effective... if an app or operating system only uses one of those cores, then the second core doesnt even come in to it.
Oh, and i have a Galaxy SII, just so you know.
As the quote is "it’s fastest model yet" the addition of the apostrophe, and subsequent contraction, can actually be read as "it is fastest model yet". It could be construed that it is either the fastest Arc, fastest Xperia, fastest Sony or fastest Android.
"its fastest" would certainly mean the adjective is applied to the object of the sentence.
