Greetings!
Recently, I've been thinking about getting an ultrabook, and have looked quite a bit at the 2013 s7. My other top choice right now is the Sony Vaio Pro 13, but I'm pretty hesitant about that due to the apparently ongoing issues with wi-fi and serious fan noise... Anyway, before I pull the trigger on an s7, I'd like to see if I can have a few questions answered.
One is about CPUs, and the choice between the i5 and i7 cores. Obviously the latter means more processing power, but I've seen some reviews (not just of the s7, but of other ultrabooks) claim that the practical difference is pretty insignificant. And in addition, I saw a claim in a thread on another forum that the core i7 model gets lesser battery life, by about an hour, but no one there definitively confirmed or denied that. Can anyone here offer insight into either of those things? Even if the real-world processing power is quite similar, it might still be worth it to get the i7 for the larger SSD, but the potential battery issue gives me pause...
My other question is about the weight, not of the laptop, but of the power brick/cord. This might seem silly, but I have a netbook with a power cord that weighs only 6.6 oz, and on the other side of the spectrum, an older Mac laptop with a power cord weighing nearly a pound (13.7 oz). So they can really vary! I'd assume the power cord on the s7 doesn't weigh too much, but I thought I'd see if anyone could tell me what it was, just so I'd know what kind of weight I'd be adding to the (wonderfully light!) laptop itself by carrying the power cord around.
Might have more questions later, but that'll do for the moment. Thanks in advance for any info!
