New Airport base station

Though Steve didn't mention it during the Keynote, Apple just added a new Airport Extreme base station to their site.
It brings two new features that justify a slight price increase (€ 179) compared to the former model :
- 802.11n : based on a draft of the next wifi standard that's not finalized yet, it will increase both range and flow (theoretically twice and 5 times more).
- Sharing a USB drive, connected to the base station USB port.
- switch 3 ports 10/100Mb.
The USB port is the same that already allowed sharing a printer. With a USB hub, it might be possible to share the 2 peripherals at the same time.
As for the 802.11n, most of the Mac are already compliant to this new standard in their integrated wifi card. A next Mac OS X update should activate it.
Delivery is due for February, yet it is possible to order it right now on the Apple Store.
[Upd.] On the following link, http://www.iphone.org/airportextreme/specs.html, you may read that the base station will be delivered with an update that activates the 802.11n functionalities on a Mac !
The compatible machines are all the Core 2 Duo Mac (except the 1.83 GHz 17" iMac) as well as the MacPro.
