I care about amiga stuff, I don't give a f**k about linux. My HD videos play faster on MorphOS than on OSX and files are copied faster. I bet that videos are played faster than on linux too. But you wouldn't care anyway since you like linux and you have more fun typing cryptic commands on a shell so I doubt you know what a responsive system is. Even xfce feels slow compared to any Amiga desktop.
In terms of general usefulness, I think some Linux distros are way ahead of MorphOS even without a desktop environment. I get along quite fine with it on modest hardware with just ratpoison/openbox, and if there's something I want to do, I can rest assured that there's an application for it in the package repository. But I agree that MorphOS is much more responsive and lightweight, and seems more swift however you look at it. Typing cryptic commands on a shell isn't all that bad if it's the fastest way to get a job done.

Either way it is, it seems reasonable to ask you to back up hard claims with hard numbers, though!
I was looking at the list of features again, seeing the FUSE wrapper library. Does that mean I get to SSHFS? Seems like a killer feature to me.
