i'm sure everyone is tired of hearing me rant about how much i love my airport card, but what they don't know is at home i use 50 feet of ethernet cable.
my place is a bachelor, so i just tuck the cord under my big rug and i'm fine. no tripping, nothing.
but my airport card is great for school since they have WiFi set up, so i can just bust out my ibook in the hallway and surf away. and teachers love it when i look up things while they're talking to help them out or prove them wrong. lol
and, in Vancouver anyway, there are a bunch of cafes/stores that have WiFi access thru a private company. so you pay for an hour, or a monthly plan or whatever and you can go out to your fave coffee place and surf away, which is fantastic if you don't wanna be restricted to your house all the time.
i guess my point is you don't NEED to buy the base. i have the card, and i'm doing fine. and i don't plan to buy the base any time soon. not on my student budget anyway.
so, that's my two cents. (deposited into your account wirelessly.)
