"Just works" in computing is an illusion. Modern computers have enough complexity and potential failure where their internal (usually software) components interact that they must be maintained and sysadmin'd. And if you're not doing that yourself, you're delegating that task to someone else—typically the OS vendor. That's why Microsoft considers Windows a "service" and will force updates at the least convenient possible time. That's why Apple has set up restrictions on running arbitrary software, even on Macs but especially on iDevices. The cost of having a device that seems to "just work" is a device you don't really own.
