Most people don't look at bench(marketing) at all. Most people just want to know if a machine can use MS Office and check emails and facebook. The specs don't get the average user that far at all, only to the point where they feel confident in their purchase.
Since we are nerds, that waste our time talking about specs on machines that have no benchmarks, aren't out on the market at all, and in many cases are just rumors, specs and benchmarks matter to us. We want this much RAM and this much HDD space, and this much GFX memory at this temperature and so forth. When, all in all, benchmarks, and the announcement of new hardware that won't ship until mid January is all about advertisements.
A few months ago Dell gave some tech news site an image of a concept display and the specs of said concept, and everyone was on the horn about how Dell's monitors are this and that and Apple is this and that and I am so

at Apple for this and blah... and nothing was said since.
This machine is very nice, and I would get one if it weren't for Windows, but it won't even ship with new hardware until January, when the new MBPs are supposed to come out. So this machine isn't competition for the current MBP, the next one will be it's competition. Then, when Apple doesn't meet our expectations, we can commence the bit** session about how Apple didn't grant us our wishes.
Just checked out the Dell site and spec'd me a 1530... sweet... now I will see Apple's answer to it and see if I get disappointed. The 250GB drives standard may be in the next MBP, but i'd rather have 200GB @ 7200 rpm standard. The price came to about $1700. I can see a 1730 out with that design pretty soon too.
