Ok this product is a joke. Apple has a bad enough record with routers as it is (My 10 month old router still does not allow Elizabeth’s VPN to connect, wheres linksys and d-link do) but check this scenario out:
Back up to Time Capsule, oh laptop kernel panics. Reboot. Wait 9 hours while it scans disk and backup over wifi.
Hard disk fails for some reason. Oh explain to the wife/etc that you have no network for days now while hard drive is replaced in router.
ROFL What were they thinking? Don’t buy this. Wait for them to fix the external port on the current base station, or support Macs as time machines over wifi.
