Unlike the old interface, the new one doesn't tell you how many inactive devices you have over a configured time period.
The old one would alert me (based on the default 14 day setting) if any devices hadn't checked in for 14 or more days, the new one requires me to sort the list by "Last Connected" in descending order just to get the same information, which isn't an 'at a glance' type display like the old one was.
