i am in the US. i saw this notebook at local BestBuy last week. i can share some of my opinion.
the build quality is very good. in my opinion, it is better than the FJ, FE, and the 15inch one from Sony.
compare with SZ. the SZ is thinner. some people mention about carbon case and LED LCD, which only available on top end model and cost a lot more than basic model. in my opinion, the LCD is at the same quality as basic model SZ.
because the C-Series is thicker, it feels stronger than SZ.
SZ can switch between nVidia 7400 and Intel 950 graphic. C-Series can't.
C-Series can take out the Hard drive!! SZ can't. SZ need to open the case and void warranty to do any hard drive swipe. (i think this is a big win for C-series)
SZ can choose webcam. and C-series can't.
i think the C-series is a very good deal. i am considering to get one with a Microsoft Webcam for notebook or a Macbook black.
