I already use two of their nas's for time machine backups (and lots of other things) so I know they understand how to interface reliably with macs, and the two nas's have worked super-reliably for years, get frequent software updates, and the interface is very nice.
This router seems to have a lot of interesting features that even Apple doesn't have. couldnt replace the airports express I use for music streaming, but I don't use those to provide wifi access so those could stick around until they die anyway, regardless of improvements to the 802.11 spec.
