Seems pretty sweet so far. I really like the LXDE/Openbox combo. Very clean, very lightweight. Linux Mint itself did not include a ton of "fluff" that I'd have to go through and delete. The only thing I'm not liking so far is the horrid fucking notification OSD popups....All distros should abolish them.....
I'm probably going to jump off of the Ubuntu ship because I do NOT like Unity. At all.
I thought it was great, because it had all kinds of media/internet ready stuff already installed, but then, I haven't been on any other Ubuntu systems lately.
