AirPort Express Base Station questions

I'm considering getting an AirPort Express Base Station with 802.11n, but I have a few questions before I buy it, I downloaded the manuals from Apple's site but I don't see this information anywhere:

I'd like to know:

Approximately how long it takes to bootup after all the settings have been set up (The area I am thinking has power port tied into the light switch, so when the light switch of the room is turned off the power to the equipment is as well).

If the device will remember settings if it's powered off for a while or if it resets every time it's out of power (tied in with the above concern).

Can multiple PC's with iTunes connect to the AirPort Express? Not at the same time, of course.

i dont own one personally, but i'm assuming its like every other router out there. it remembers settings unless physically reset (holding the button for 10-15 seconds).

Yes it will remember its settings after a power-off and yes you can connect multiple PC's.

I'd say it takes ~30 seconds to "boot," yes it will remember settings and yes, any computer with iTunes on the network will be able to use airtunes to airport expresses connected to said airport extreme...and one computer can connect to multiple expresses (ie multi-room audio)
