OK, review done. The Airport Extreme is clearly faster, and the Express
IS bottle necked by the 100Mbps port. Graphs in the review post.

Nicely done. If I'm not mistaken, MB/s can be converted to Mb/s by multiplying the number times about 8.4, which means that the Express was maxing out at about 96Mb/s throughput on that file transfer which would seem very, very good for a 100Mb/s port.
Not sure if it should matter, but did you also try transferring the file *from* the server *to* the laptop? I'd be interested to see if the numbers differed significantly.
The data that I found most interesting was the 2.4GHz vs 5GHz tests. As throAU stated, 2.4GHz should have a range advantage over 5GHz, so I might have expected to see that translate to a speed advantage in your long-range test, but perhaps your long-range distance isn't 'long enough' and perhaps so long as you can get *any* signal on 5GHz (even one bar) it will outperform a stronger 2.4GHz signal? Just guessing here.
Can someone confirm if it makes sense to allocate some devices to 2.4GHz and others to 5GHz just to portion out the burden of the two wireless bands? With my Extreme I think I've been configuring our laptops to use the 2.4GHz band and the iOS devices (iPhone, iPad, and non-ethernet-connected AppleTV's) to use the 5GHz band. If anyone thinks I should just use 5GHz for everything, please advise.
Some other questions...
So, can a 2nd AirPort Extreme also be used as a network extender, or do you *have* to use the Express for that purpose?
Also, one thing I found surprising on Apple's site is that you can extend your network with the Express without physically connecting the Express to the Extreme (it will just pick up the Extreme's signal wirelessly and then extend it). Was that true of the old Express as well? Regardless, if you can physically connect the main unit to the extender, I would think you'd be best to do so.
