I currently have the older Airport Extreme that's only Wireless N. I bought it in 2011 and it's the flat mac-mini sized base station. It still works great but recently realized all my devices are now AC capable. Would it benefit me to upgrade? I kind of like the newer design as well since it has a smaller footprint, but taller, taking up less room on my shelf. Is it well shelling out the nearly $200 for it now in 2016? Thanks
