I tried Sidux for the first time, and I'm REALLY impressed... It's lightning fast!!!
I'm not sure why, but it boots to desktop so quickly you'd say something is not right.
And it's the snappiest desktop experience I've had.
And, it has a script - smxi - that does graphic driver install&configuration, kernel choosing, distro upgrading, cleaning, adjusting, safely removing and more.
And, it's rock stable AND bleeding edge.
And, it has a very informative manual.
In short: I (humbly) suggest that Clem & the Crew take a deep look at Sidux; it's a different philosophy than Mint, but it could provide a couple of ideas, I think.
Otherwise, it would just be interesting to hear your impressions.
