Welcome. I'm a Mint n00b too, but I've been using Ubuntu for a couple of years so I'm not new to Linux.
I dual booting Win7/Mint 11 on a new Acer ultraportable I just got. Not that i use Win7- I can't stand it. But I'll leave it there until the warranty is up, just in case.
I am liking Mint so far. A lot more stuff works "out of the box" than in Ubuntu. So far it's been fast and stable. I think if you really give it a chance and work through any minor issues you might have you'll enjoy your Mint experience.
There's a lot of smart folks here willing to help.
