Yesterday I put together a new computer and installed both this release, and Windows XP 64-bit edition, as dual boot.
I would have to say that I absolutely love the ease and speed with which the Mint installed as compared to Windows. Much less total time, and many fewer interactions needed between the non-interactive portions of installs. Plus Mint has better partitioning support.
The only problem so far has been the WLAN setup. I have a year old WG311 card that ironically has no OEM drivers for XP 64-bit either. So the only problem I've had with Mint is the same I'm having with XP. I also used the Mint installation to download drivers, using the embedded NIC, for the MB that were needed by XP. I didn't have much time last night to figure out the WLAN, but I'm sure I'll get it working today (hopefully on both OS).
Edit (the next day): After trying to get the WLAN to work for a couple of hours, I decided to reinstall Mint, this time with the WLAN card installed. I'm happy to say it installed perfectly and selecting and logging into the wireless router was matter of two clicks and a password entry. (I did also manage to get it to work under XP, but that had it's own troubles.)
