Supposedly everything has already been said, but not yet by everyone. Therefore, I prefer to go at this point to a few criticisms and weaknesses of 530U3C, and add a bit of information that I had not read before buying in reviews. On the one hand has my laptop on the right side a slight gap to the folded state. However, I would be probably much later (or not) have noticed, I had not seen immediately afterwards. I have to say he does not interfere in any way and reduces the feeling of having a very high technology-quality piece in your hand. A little I miss the opportunity to attach a Kensington lock, which have probably only the 14 'models. Comes in handy when you want to use his laptop sometimes not in home environments and prevent it too easy to find new followers. Initially made me who expresses even wireless throughput annoyed (about 20 KB / sec max with disconnects). This is probably due to a driver error in 802.11n and can be prevented if you instead only 802.11b + g uses. The latter set at my Fritz box, the laptop now transmits with much more acceptable 330 KB / s (with two intervening concrete ceilings). As a very "quiet environment-friendly" I feel the Fn-key combination that immediately puts the laptop into a mode in which the fans are more or less inaudible. To what extent by the CPU is throttled me is not yet clear, but in such situations also secondary.
Conclusion: great design, ample power. For me, in spite of (bypassable) wireless Error absolutely the right decision.
