> Being able to run a mainline kernel means being able to receive updates indefinitely I wouldn't say indefinitely. Hardware that runs Linux today, mainline or not, is not guaranteed to continue to run newer kernel releases. Drivers and even whole architectures do get dropped from the tree, though they get reverted if anyone actually notices and still cares about such support. While indefinite sounds nice, it turns out that indefinite support is not quite what people actually want in practice, even if they exclaim otherwise. Typically, because then they're responsible for maintenance, and the common response there is "no thanks." I'm all for getting everything upstream though!
