You will not be very happy with Jaunty.
The Ubuntu dev team is working hard to ready an update that will fix all these known issues, so I'm not particularly worried about it.
As for whether Linux Mint should be based on Debian, I STRONGLY DISAGREE. Ubuntu is known to be the best supported Linux Distro out there in terms of hardware, documentation, vendor support, etc. so keeping the binary compatibility between Linux Mint and Ubuntu is crucial. Sure Ubuntu is not as bug-free as Debian but that's the only thing Debian does better than Ubuntu. I mean, if we really want Linux Mint to be a user friendly distro, we should stick with Ubuntu.
