"in comparison; the ARM boards tend to get discontinued quicker"
This is true though I believe it's mainly due to them being newer developments in a field (mass produced embedded boards) where everyone and their cat makes something new every month. It's a moving target that will never settle (luckily) but given enough time it will slow its pace to sustainable levels both for manufacturers and users/developers. Give it some time, the kid is young.
As an example, I'm still waiting for a cheap enough board around which I would build what I consider a vital brick in every home network: something with enough SATA ports to make a RAID enabled server, then would cut costs in all other corners. Say 4 to 5 SATA ports, no video, no audio, no WiFi, no multiple NICs (I'd use a separate board for firewalling), no more than a serial port for monitoring and few GPIOs for blinking some leds or drive fans, monitor UPSs etc. It would be the best possible platform to make cheap non trivial file servers.
My current configuration is 2+2 disks arranged as RAID1 (I don't trust anything else) kept in sleep mode when not in use for more than 2 hours plus a fifth disk used very often as temporary storage before things are being stored on the RAID. I use a cheap Atom Mini ITX board I purchased used on ebay plus a rack enclosure that weighs like a ton. Nas4Free is the OS, which is perfect for the task although RAM usage with XFS reaches the maximum available on that board (4GB), but for home use it's still ok. It works perfectly, but I would happily swap it for a lighter ARM system in a smaller box. Unfortunately it looks like there's no solution to be used to build a similar file server, except costly boards with a lot other peripherhals or much faster CPUs I wouldn't have any use for. So why nobody makes a board like that? I would guess they analyzed the market and concluded there'not enough demand.
A board like that would mean an excellent home/SOHO file server at a third of the price, but apparently the small number of people who build their own file server doesn't justify any risks in that field.
