@ Nick Cassidy
I've only ever used it on systems which were sold with it pre-installed by large manufacturers, so I haven't had any lack of power / lack of device support issues. I've just had crappy OS design issues. I guess your definition of never missing a beat includes incredibly slow copying of files, the inability to retain settings over time, opaque user management requiring a suck-it-and-see approach to addressing problems, and an appallingly bloated and inefficient network stack.
In which case, good luck to you.
