If you own a Mac with wireless N its your best choice by far. The built in OS configuration tool is well executed. Networking wise I have zero issues with my gigE AEBS. Works great even with the 7.2.1 firmware. I think I had to manually configure a NAT port for Azureus but thats about it. If you are even moderately networking savvy you will have zero issues with it.
The big issues seem to be with the 'addon' type stuff in the disk and printer support. My experience at least is that AirDisk works perfect using a Lacie Porsche enclosure with a 500GB Seagate drive. I think the enclosure model/drive is a big factor so YMMV with this feature. Also on the downside is that AirDisk transfer rates are limited by the speed of the AEBS CPU. You will never see more then 9MB/s or so read or 4.5MB/s write no matter what connection method you use. Still this is pretty good and more then enough for archival use.
As stated lack of a real firewall and logging is a bit annoying however OSX Leopard has a very nice inbound firewall built in and you can (and should!) use Little Snitch to monitor your outbound so the primary issue is not so bad.
