For the two boards I used to maintain (Zeus and Viper), I'm happy to see them go. Should anyone want to take over and bring them into this decade, I'm happy to provide the HW I still have (although getting HW was never a problem with PXA, and it probably is simply that people have, just like I did, lost interest).

I still have a Netwinder that I switch on once in a while to check that it is still alive (I last booted 5.18 on it, and maintain a couple of ugly hacks to allow an old Debian to run on it). This isn't a practical machine by any modern standard, but I'd like to keep it around for the same reasons I still have an Alpha LCA4 (nostalgia).
