I'll put in an ebay search notification for when the R650 (and R750) for $50 each and maybe it'll ding in a couple years and I'll be in a place to swap out the 3802 network I've got running now...
As far as I can tell, in this one case (with mobility express) it seems like Cisco accidentally did something overall (IMO) "good" for the world by making it possible for their kit to be reused by some part of the world where someone will get utility out of the still very nice equipment and somehow cisco won't see a dime from that "someone is using cisco equipment" event.
Mobility express isn't perfect, but considering the cost of the gear and the cost of the license, it is pretty darned good. I suspect some product manager at cisco got fired for accidentally making the world not quite as bad a place as it could be if cisco extracted license fees on all the 2802, 3802, and 4800 access points or otherwise sent them to the e-waste bin 4 years early.
