So far, I'm impressed with the range gains on the new 802.11ac Airport Extreme unit. My entire apartment is now covered reliably, whereas before I was having some slowdowns below my internet speeds in areas with the older unit.

Also good to note, the new Airport Extreme now officially supports doing Time Machine backups to a USB attached disk, per the manual.
