This. I just decommissioned 5 x AP and 2 x backhaul radios this summer from Ubiquiti at a remote site I manage. These were all purchased and installed in 2011. I replaced them all with newer equivalents, not because they weren't working or weren't receiving updates - but because I'm 4 hours from the site and told the owner they've gotten their ROI and needed to preemptively replace. This happens to be my in-laws place and I don't want to deal with replacing some outdoor radios in the middle of a Midwestern winter. I sold all the gear as a package for about $150 and the buyer was well aware of the age and the fact that 3 of the devices had been outside that entire time. I commend Ubiquiti on the commitment to their line of products and the updates all devices that were in service continue to receive.
