Well, perhaps they could make use of that usb port to offer expansion hardware that can accomodate stuff like that. Or maybe a whole new esc in the future with extra options. I don't personally want to shell out the money for a dedicated logger or a speed meter as it has some interesting data, its nothing that I need to have or make use of enough to justify the cost. So I thought if they could make a basic one built into the esc, it would be cool to have.
