I saw it mentioned in an answer here about firesheep, but I've never heard of it -- Should WPA2 be presumed insecure?
WPA2-AES should be considered secure against "outsiders": people to whom you have not given the cryptographic key / passphrase.
WPA2-AES is not secure against "insiders". People who you have given the cryptographic key can access the network and may be able to eavesdrop on communications of other users. However, usually this is acceptable and beyond the scope of what we are expecting the network to do for us.
Also, make sure you read about the vulnerability in Wifi Protected Setup (WPS). Probably you'll want to disable WPS. See, e.g., this question for some citations where you can read more about the WPS vulnerability.
