I've installed Mint 7 x64 and use it since the ISO got out, I put it on an USB stick via Netbootin in Windows, installed it from there, works fine. Mint Menu works fine, Mint update also. The Grub background and the desktop background are very beautiul and suitable to the overall design! Nice! Kudos to the wallpaper designer!
Bugs I've encountered:
- Rhythmbox hangs for 4-5 seconds while switching songs (i have 4000+ songs in my library) - it's because I installed the newest one from GetDeb, reverting to the default one and everything works again

- Totem sucks! Doesn't advance to next movie/song in the playlist (tested also with Repeat and Shuffle options, but no avail), often then the position bar stays at the end and doesn't correspond to the current playback progress. I've removed it and added VLC ppa and installed VLC 1.0.0
- I can't remove evolution-data-server-common and the deskbar-applet - I don't want them installed at all

! Any ideas how to remove them?
Thanks Clem and the others from the Mint development team! It's a great release! I finally upgraded from Mint 5 x64! Mint 6 x64 had too much bugs...
Oh yes, and thank you for finally changing the theme and icons! IMO you can drop all the old ones, these new ones are a LOT better for my eyes!
