It's easy to envy the Swiss, what with the fine chocolate and the neutrality and such. Now, another reason to long for the refined air of the Alps: the Swiss version of the Apple Store website is indicating availability on the supercharged 802.11n version of the Airport Express, as yet unnannounced in the US of A (translation here). With the domestic Apple Store showing 1-2 week ship times for the AE, we might well expect to see the new device next week, possibly on, I dunno, Tuesday.
Connectez-vous à Internet, imprimez et diffusez de la musique depuis iTunes dans n'importe quelle pièce de la maison. Le tout, sans fil. Désormais avec le standard 802.11n1.
Avec AirPort Express connecté à votre modem ADSL ou câble, jusqu'à 10 utilisateurs peuvent surfer sur le Web, envoyer des e-mails et faire bien d'autres choses encore... en même temps2. AirPort Express est basé sur la nouvelle spécification Wi-Fi 802.11n, qui multiplie jusqu'à cinq fois les performances et par deux la portée du standard 802.11g précédent3.

Remarques.
(1) La Borne d'Accès AirPort Express repose sur une version préliminaire de la spécification IEEE 802.11n. Elle est compatible avec les normes IEEE 802.11a, IEEE 802.11b et IEEE 802.11g.
It is my understanding that if 'B' device is connected to a 'G' network, the whole network bogs down to 'B' speed. Correct?
So, if I upgrade to an 'N' network since my MBA is N-equipped, what happens if I connect a G-level device? Does the whole thing slow down to G, or do G devices run at G speed and N devices at N speed???

Good question. My understanding is yes, the slowest component will slow everything down.
This was on the fine print on the Apple Extreme page.
Based on a comparison with Apple's 802.11g products. Comparison assumes AirPort Extreme network with 802.11n-enabled computer. Speed and range will be less if an 802.11a/b/g product joins the network.
BTW, glad to see Apple Canada pricing this thing the same price as the U.S. store.
It is also of note that "N" is not a standard yet, and it is still in the draft process until November. I'd be reluctant on spending too much money on something that may not work without special upgrades (like the "N" enabling scam). This is something that I had just read about the other day, though I would expect little change to the proposed standard, since they are marketing devices that claim to be "N", even though "N" does not really exist.
But if "B" and "G" speed connections slow down the device, it is more than compensated by the fact that an "N" speed device can handle simultaneous channels, thus one would have less speed loss with multiple "G" devices than running a straight up "G" device, as far as I understand. And since it is Ethernet in the first place, your mileage will vary and you will never be able to use the full signalling speed anyways...
